A basketball player is standing on the floor 10.0 m from the basket as in Figure P3.47. The height of the basket is 3.05 m, and he shoots the ball at a 40.0 angle with the horizontal from a height of 2.00 m. (a) What is the acceleration of the basketball at the highest point in its trajectory? (b) At what speed must the player throw the basketball so that the ball goes through the hoop without striking the backboard?
A student stands at the edge of a cliff and throws a stone horizontally over the edge with a speed of vi= 18.0 m/s. The cliff is h = 50.0 m above a body of water as shown in Figure P3.19. (a) What are the coordinates of the initial position of the stone? (b) What are the components of the initial velocity of the stone? (c) What is the appropriate analysis model for the vertical motion of the stone? (d) What is the appropriate analysis model for the horizontal motion of the stone? (e) Write symbolic equations for the x and y components of the velocity of the stone as a function of time. (f) Write symbolic equations for the position of the stone as a function of time. (g) How long after being released does the stone strike the water below the cliff? (h) With what speed and angle of impact does the stone land?
H3.6. A bullet is fired from ground level at 120 m/s in the +55° direction. The bullet hits the ground x meters away. Setup with three completely labeled diagrams, the first showing the trajectory of the stone, the second its vertical motion and the third its horizontal motion. Calculate the vertical and horizontal components of the initial velocity. Using the formula (y = v0yt …) and obtain the time interval the bullet travels through air. Calculate how far from the point that it was fired the bullet will hit the ground.
You hit a golf ball from the (level) ground, with an initial speed and an initial angle. Ignore air resistance. (This is very unrealistic.) The initial speed is v0 = 23.7 m/s, and the angle the ball is hit at is θ = 46o. Calculate vx0, the initial horizontal component of velocity (in m/s). What equations describe the trajectory of the golf ball?
Consider a projectile being launched with an initial speed of 49.5 m/s at a variety of initial angles. Refer to the figure. Part (a) What is the range, in meters, of the projectile if it is launched at an angle of θ1 = 70.6°? b. What is the range, in meters, of the projectile if it is launched at an angle of θ2 = 38°? c. What is the range, in meters, of the projectile if it is launched at an angle of θ3 = 90 − 70.6°, the complement of θ1?
т A cannon sits on a horizontal plain, angled up at 35°. A cannonball is fired with a velocity of 100“. The cannonball hits the ground at the same height from which it was launched. a) What is the maximum height of the cannonball? (Answer: 168 m ) b) What is the flight time of the cannonball? (Answer: 11.7 s) c) What is the horizontal range of the cannonball? (Answer: 959 m) d) What is the impact velocity in magnitude and angle? (Answer: 100@35° below x-axis)
Trachecktory. Two cannonballs, aptly named a and ß, were launched on level ground. a was launched with a velocity of 18.0 [m/s] at 36° with respect to the ground while ß was launched with a velocity of 17.6 [m/s] at 48° with respect to the ground. What can you say about a and ß's range and time of flight? O a and ß do not have the same range; a has a larger time of flight. O a and ß have the same range; a has a larger time of flight. a and ß have the same range; ß has a larger time of flight. a and ß do not have the same range; ß has a larger time of flight.
Use the component method to add the vectors A and B shown in Figure P3.9. Both vectors have mag- nitudes of 3.00 m and vector A makes an angle of 0 = 30.0° with the x axis. Express the resultant Á + B in unit-vector notation.
I have no idea to how to start to this question: Wags (a dog) decides to go on a journey. He begins his journey by traveling 58 meters in a direction directly south. He then runs 100.0 meters in a direction 30◦north of west. During the last leg of his journey, he follows a scent for 59 meters in a direction 30◦east of north. What distance does Wags end up from his initial startingpoint?
A Canon launches a target at 40°. My distance of the x value is 4.60m. My distance for the y value is 1.1670 meters. The distance total is 4.746 meters. The problem is asking me to figure out the time of the object in air.I don't have velocity, I know the velocity initial is more than 0 and that the velocity final is zero. If I want to find time, I would need to use a vector diagram of velocity and use the resultant as my velocity. However, I have no idea what the velocity of Y or velocity of X. I only know that the velocity of X is in equilibrium and is constant as well as knowing that velocity final is zero. Oh yeah also velocity initial is velocity of the x value.
A student standing on a cliff that is a vertical height d = 8.0 m above the level ground throws a stone with velocity v0 = 22 m/s at an angle θ = 17 ° below horizontal. The stone moves without air resistance; use a Cartesian coordinate system with the origin at the stone's initial position. a)With what speed, vf in meters per second, does the stone strike the ground?
The equation r(t) = ( sin t)i + ( cos t)j + (t) k is the position of a particle in space at time t. Find the particle's velocity and acceleration vectors. π Then write the particle's velocity at t= as a product of its speed and direction. The velocity vector is v(t) = (i+j+ k.
