A ball is released from rest at the top of a 30.0 m tall building. How long does it take to strike the ground? How fast is it moving when it strikes the ground?

A ball is thrown horizontally from the top of a 71.6-m building and lands 147 m from the base of the building. Ignore air resistance. How long is the ball in the air? Select the correct answer     1.82 s         1.20 s   Your Answer     3.32 s     3.82 s     0.473 s

A friend of yours has a one story house with a pool in the backyard. Someone gets the bright idea to jump from the roof of the house into the deep end of the pool. a) If the roof of the house is 16 ft tall and the horizontal distance between the edge of the house and the pool is 10 ft, what would the jumper's minimum velocity need to be to land in the pool? b) Let's assume your friend can jump with an initial horizontal velocity of 15 ft/s. What is their total velocity when they hit the water? (hint: determine both the x and y velocity components, find the resultant)

A ball is thrown horizontally with a velocity of 5 m/s from the top of a tall cliff. Neglecting air drag, a) What is the speed of the ball 2 seconds later. b) What vertical distance has the ball fallen 2.0 seconds later? You must include a sketch to solve
