Problem A) A penny is thrown vertically upward with a speed of 13 m/s. Exactly 2 seconds later a nickel is thrown upward along the same path as the penny at a speed of 15 m/s. Ignoring air resistance, (a) at what time do the penny and nickel collide? (b) At what height does the collision occur? (c) Is the penny on its way up or down when the collision occurs?
A ball falls from height of 19.5 m, hits the floor, and rebounds vertically upward to height of 15.0 m
A ball falls from height of 19.5 m, hits the floor, and rebounds vertically upward to height of 15.0 m. Assume that mall 0.390 kg. (a) What is the impulse (in kg. m/s) delivered to the ball by the floor? (b) If the ball is in contact with the floor for 0.0400 seconds, what is the average force (in N) the floor exerts on the ball?

A tennis ball is shot straight up from the ground. After traveling 4.00 m, the ball passes a 4.00 m high window and then continues straight up until it loses all its upward velocity and falls to the ground. During the last second of its flight before it hits the ground, the ball drops 20.0 m. a) What is the maximum height above the ground reached by the ball? b) What is the total time for the ball’s flight? c)...

A package is dropped from a helicopter moving upward at 1.5 m/s. If it takes 16.0 s before the package strikes the ground, how high above the ground was the package when it was released if air resistance is negligible? Give your answer in meters.
An object is thrown upward from 1 m above the ground. It travels vertically up, reaches a maximum height of 2.5 m above ground
An object is thrown upward from 1 m above the ground. It travels vertically up, reaches a maximum height of 2.5 m above ground, falls back down, and is caught at exactly the same position it was thrown 1 s after it was thrown. What was the average velocity of the object? Click the answer you think is right 1.5 m/s 0 m/s 3 m/s
