A ball is thrown straight up. It passes a 2.00-m-high window 7.50 m off the ground on its path up and takes 1.30 s to go past the window. What was the ball’s initial velocity?
A diver bounces straight up from a diving board, avoiding the diving board on the way down, and falls feet first into a pool. She starts with a velocity of 4.00 m/s and her takeoff point is 1.80 m above the pool.
What is her highest point above the board?
How long a time are her feet in the air?
What is her velocity when her feet hit the water?
A hot-air balloon rises from ground level at a constant velocity of 3.00 m/s. 60.0 seconds after liftoff, a sandbag is dropped accidentally from the balloon.
Calculate the time it takes for the sandbag to reach the ground.
Calculate the velocity of the sandbag when it hits the ground.
