A golfer is attempting to hit a golf ball from a sand trap into a hole that is 3 m away (Figure 1). The hole is on a green that is at an elevation of 0.3 m above the sand trap. If the golfer hits the ball at an angle of θ = 60∘ above the horizontal, (a) what must be the speed v0 of the ball for it to go directly into the hole without rolling along the green? (b) How long is the ball in the air? (c) What is the final speed of the ball just as it enters the hole? (d) At what angle is the ball traveling just before it enters the hole?

You are exploring a distant planet. When your spaceship is in a circular orbit at a distance of 630 km above the planet's surface, the ship's orbital speed is 5500 m/s. By observing the planet, you determine its radius to be 4.48×106m. You then land on the surface and, at a place where the ground is level, launch a small projectile with initial speed 12.6 m/s at an angle of 30.8∘ above the horizontal. If resistance due to the planet's atmosphere is negligible, what is the horizontal range of the projectile?
You are on a space station, in a circular orbit h = 500 km above the surface of the Earth. You complete your tasks several days early and must wait for the next mission from the surface to bring you home. After days of boredom, you decide to play some golf. Walking on the space station surface with magnetic shoes, you tee up a golf ball. You hit it with all of your might, sending it off with speed υrel, relative to the space station, in a direction parallel to the velocity vector of the space station at the moment the ball is hit. You notice that you then orbit the Earth exactly n = 2.00 times and you reach up and catch the golf ball as it returns to the space station. With what speed υrel was the golf ball hit?
A baseball slugger smacks a pitch and watches the ball float into the bleachers for a home run, landing h=6.5m higher than it was struck. When visiting with the fan that caught the ball, he learned the ball was moving with final velocity vf=31.5m/s at an angle θf=28∘ below the horizontal when caught. Assume the ball encountered no air resistance, and use a Cartesian coordinate system with the origin located at the ball's initial position. Part A: Create an expression for the ball’s initial horizontal velocity, V0,x, in terms of the variables given in the problem statement. Part B: Calculate the magnitude, in meters per second, of the vertical component of the ball’s initial velocity and the magnitude, in meters per second, of the ball’s initial velocity. Part C: Find the angle above the horizontal, in degrees, at which the ball left the bat.
You are exploring a distant planet. When your spaceship is in a circular orbit at a distance of 630 km above the planet's surface, the ship's orbital speed is 4900 m/s. By observing the planet, you determine its radius to be 4.48 x 10° m. You then land on the surface and, at a place where the ground is level, launch a small projectile with initial speed 11.6 m/s at an angle of 30.8° above the horizontal.

Problem: A person who is 1.3 m tall throws a ball with a speed of 19m/s at an angle of 17 degrees above horizontal. One part of the problem asks me to find the x and y components of the ball's velocity before it hits the ground. I have tried using the vy^2 = voy^2 + 2ah for the y-component: vy^2 = (5.56)^2 + (2)(10)(1.3) = 7.54 and my x-component is just (19)(cos(17))= 18.17 m/s, but it is saying this is not the right answer. What am I doing wrong?
You are a visitor aboard the New International Space Station, which is in a circular orbit around the Earth with an orbital speed of ?o=2.45 km/s�o=2.45 km/s . The station is equipped with a high velocity projectile launcher, which can be used to launch small projectiles in various directions at high speeds. Most of the time, the projectiles either enter new orbits around the Earth or eventually fall down and hit the Earth. However, as you know from your physics courses at the Academy, projectiles launched with a sufficiently great initial speed can travel away from the Earth indefinitely, always slowing down but never falling back to Earth. With what minimum total speed, relative to the Earth, would projectiles need to be launched from the station in order to "escape" in this way? For reference, recall that the radius of the Earth is ?E=6370000 m�E=6370000 m, the mass of the Earth is ?E=5.98×1024 kg�E=5.98×1024 kg , the acceleration due to gravity on the surface of the Earth is ?=9.81…
on december 25, 2004, during a NASA mission to Saturn, the spacecraft Cassini released a probe named Huygens, which landed on the Saturnian moon titan on January 14, 2005. huygens was released from the main spacecraft at a gentle relative speed of 31 cm/s. As Huygens moved away, it rotated at a rate of 7 revolutions per minute.(a) How many revolutions had huygens completed when it was 150m from Cassini? (b) How far did Huygens moved away from cassini during each revolution? give your answer in meters
A space shuttle is in a circular orbit at a height H above the Earth. A small satellite is held above the shuttle (i.e. directly away from the Earth) by means of a rod of length h and then released. What is its initial motion relative to the shuttle?

When it is 10 seconds into its flight, the following radar measurements are recorded: r = 2970 m, ř = 449 m/s, ř= 4.08 m/s?, 0 = 18°, 0 = 0.063 rad/s, 0 = -0.0367 rad/s?. For this instant determine the angle B between the horizontal and the direction of the trajectory of the rocket and find the magnitudes of its velocity v and acceleration a.

A motorcycle daredevil plans to ride up a 2.85 m high 29.0° ramp, sail across a 10-m-wide pool filled with hungry crocodiles, and land at ground level on the other side. He has done this stunt many times and approaches it with confidence. Unfortunately, the motorcycle engine dies just as starts up the ramp. He is going 18.2 m/s at that instant, and the rolling friction of his rubber tires is not negligible. Assuming that the local acceleration due to gravity is -9.80 m/s², calculate the landing point (in m) relative to the 10.0 m edge of the pool. (-1.0 m means he was 1.0 m short and in the pool, +1.0 m means he landed 1.0 m past the edge). The coefficient of rolling friction for rubber on ramp is 0.02. Submit Answer Tries 0/10
In the figure here, a small, solid, uniform ball is to be shot from point P so that it rolls smoothly along a horizontal path, up along a ramp, and onto a plateau. Then it leaves the plateau horizontally to land on a game board, at a horizontal distance d from the right edge of the plateau. The vertical heights are h, 5.0 cm and h, 1.60 cm. With what speed must the ball be shot at point P for it to land at d = 6.5 cm? Ball Vo %D II
