A 124 kg balloon carrying a 22kg basket is descending with a constant downward velocity of 20m/s. A 1 kg stone is thrown from the basket with an initial velocity of 15m/s horizontally measured from the person in the basket. The person sees the stone hit the ground 5 seconds after it was thrown. The balloon continues its downward descent with the same constant velocity of 20m/s. Just before the stone hits the ground, what are the horizontal and vertical velocity components measured by an observer i) in the basket ii) on the ground.

9) While a vehicle is traveling with a velocity of v=8 (m/s), a stone is thrown over it with a velocity vo=10 (m/s). Since a person standing on the ground sees the stone moving vertically upwards, what is the angle 0 of the stone's shooting angle with the car surface? g 10 (m/s²)
An Olympic diver is on a diving platform 3.50 m above the water. To start her dive, she runs off of the platform with a speed of 1.3 m/s in the horizontal direction. What is the diver's speed, in m/s, just before she enters the water? m/s
When a vehicle is traveling with a speed of v = 10 m / s, a stone is thrown over it with a speed of v = 40 m / s. Since the person standing on the ground sees that the stone moves vertically upwards, what is the angle Ɵ of the stone's shot angle with the car surface? g = 10 m / s2
4. A water park is designing a new water slide that finishes with the rider flying horizontally off the bottom of the slide. The slide is designed to end 1.2 m above the water level, and the average rider is estimated to leave the bottom of the slide at 25 m/s. How far will the rider fly through the air before hitting the water?
Daniel takes his two dogs, Pauli the Pointer and Newton the Newfoundland, out to a field and lets them loose to exercise. Both dogs sprint away in different directions while Daniel stands still. From Daniel's point of view, Newton runs due North at 3.90m/s, but from Pauli's point of view, Newton appears to be moving at 1.50 m/s due East. What must Pauli's velocity relative to Daniel be for this to be true? Express your answer in terms of the ? and ?‑components if North is the +? direction and East is the +? direction. a) ?-component (m/s): ?-component (m/s): b) Express your answer as a magnitude and an angle measured counter‑clockwise from due East.
36. A rifle is used to shoot twice at a target, using identical cartridges. The first time, the rifle is aimed parallel to the ground and directly at the center of the bull's-eye. The bullet strikes the target at a distance of H, below the center, however. The second time, the rifle is similarly aimed, but from twice the distance from the target. This time the bullet strikes the target at a distance of H3 below the center. Find the ratio H„/H,.
Which of the following will reach the maximum range? a. A golf ball is hit at an angle of 90° above horizontal with a speed of 80 m/s. b. A golf ball is hit at an angle of 80° above horizontal with a speed of 90 m/s.
1. A bullet is fired from a rifle that is held 1.6 m above the ground in a horizontal position. The initial speed of the bullet is 1100 m/s. Find (a) the time it takes for the bullet to strike the ground and (b) the horizontal distance traveled by the bullet.
A cannon at an elevation of 2000 feet above sea level fires a missile upward at an angle of 45 degrees to hit a target on a boat at sea on the far side of a mountain. The missile just barely clears the top of the mountain and hits the target. The cannon is 5 horizontal miles from the top of the mountain. Ignore air resistance. a. Determine the firing velocity of the missile. b. Determine the height of the mountain. c. Determine the total range of the missile (distance from cannon to target)
Emily throws a soccer ball out of her dorm window to Allison, who is waiting below to catch it. Emily throws the ball at an angle of 30° below horizontal with a speed of 12 m/s, and Allison catches it 2.5 s later. How far from the base of the dorm does Allison stand to catch the ball, in meters

A 124-kg balloon carrying a 22-kg basket is descending with a constant downward velocity of 20.0 m/s. A 1.0-kg stone is thrown from the basket with an initial velocity of 15.0 m/s perpendicular to the path of the descending balloon, as measured relative to a person at rest in the basket. That person sees the stone hit the ground 5.00 s after it was thrown. Assume that the balloon continues its downward descent with the same constant speed of 20.0 m/s. (a) How high is the balloon when the rock is thrown? (b) How high is the balloon when the rock hits the ground? (c) At the instant the rock hits the ground, how far is it from the basket? (d) Just before the rock hits the ground, find its horizontal and vertical velocity components
