A ball is shot from the ground into the air. At a height of 9.80 m, its velocity is v = (8.50i + 4.00j) m/s, with i horizontal and j upward. To what maximum height does the ball rise? What total horizontal distance does the ball travel? What is the magnitude of the ball's velocity just before it hits the ground? What is the angle (below the horizontal) of the ball's velocity just before it hits the ground?

A ball is dropped from rest at a height h. Directly below on the ground, a second ball is simultaneously t thrown upwards with a speed of vc. The two balls collide at the moment that the second ball is instantaneously at rest. (They collide when the second ball is at its maximum height.) What is the height of the collision? At what time does the collision occur if both balls' motion stated at t = 0 s?

Problem-3 A very small but very heavy ball is thrown directly upward from the ground level with a speed of 12.5m/s. (a) What is the maximum height above the ground reached by the ball? (b) What is the total time after being thrown from the ground that it takes for the ball to reach the ground again? (c) What is the velocity of the ball when it hits the ground?

(25%) Problem 4: Consider two projectiles that can be shot upward by spring guns. Object A is made of solid aluminum and has a mass of 50 grams. Object B is made of cast iron and has a mass of 200 grams. For this problem, you may take the gravitational field strength to be g = 10 N/kg. A 14% Part (a) Masses A and B are both shot straight upward at the same time. Mass A is shot with...

Jumping up before the elevator hits. After the
cable snaps and the safety system fails, an elevator cab free-falls
from a height of 30.0 m. During the collision at the bottom of the
elevator shaft, a 85.0 kg passenger is stopped in 4.00 ms. (Assume
that neither the passenger nor the cab rebounds.) What are the
magnitudes of the (a) impulse and (b) average force
on the passenger during the collision? If the passenger were to
jump upward with a...
