Current Attempt in Progress A rocket is fired at a speed of 53.0 m/s from ground level, at an angle of 55.0° above the horizontal. The rocket is fired toward an 15.9- m high wall, which is located 18.0 m away. The rocket attains its launch speed in a negligibly short period of time, after which its engines shut down and the rocket coasts. By how much does the rocket clear the top of the wall?

Dock diving is great form of athletic competition for dogs of all shapes and sizes. Sheba, the American Pit Bull Terrier, runs and jumps off the dock with an initial speed of 9.02 m/s at an angle of 25.0° with respect to the surface of the water. Sheba begins at a height of 0.840 m above the surface of the water. What is her total time of flight up until the instant before she hits the water? Express your answer in seconds.

A rocket is fired at a speed of 83.0m/s from ground level, at an angle of 66.0degrees above the horizontal. The rocket is fired towards an 28.8m high wall, which is located 25.0m away. The rocket attains its launch speed in a neglibly short period of time, after which its engines shut down and the rocket coasts. By how much time does the rocket clear the top of the wall?

Answer parts A and B

A person stands on a diving board and tosses a stone into a swimming pool. The stone is thrown from a height of 2.9 m above the water surface with a velocity of 2.8 m/s at an angle of 38° above the horizontal. As the stone strikes the water surface, it immediately slows down to exactly half the speed it had when it struck the water and maintains that speed while in the water. After the stone enters the water, it moves in a straight line in the direction of the velocity it had when. it struck the water. If the pool is 4 m deep, how much time elapses between when the stone is thrown and when it strikes the bottom of the pool? ttotal = S

A fox fleeing from a hunter encounters a 0.770 m tall fence and attempts to jump it. The fox jumps with an initial velocity of 7.30 m/s at an angle of 45.0°, beginning the jump 1.93 m from the fence. By how much does the fox clear the fence? Treat the fox as a particle.

11.A blue person throws an object with an initial velocity of 25.0 m/s at an angle of 37.0°. A green person stands 15.0 meters in front of the blue person and throws an object straight up. Assume that both objects are thrown from the same initial elevation. a) If the green person throws their object with an initial speed of 20.0 m/s, at what time should they throw it such that it strikes the other object while it is traveling upward? Measure this time relative to when the blue person throws their object? b) If both people throw their objects at the same time, with what initial speed must the green person throw their object such that they collide? Answers: a) ~0.267 s b) ~15.0 m/s
