You toss a ball straight up into the air from an initial height of 1 m above the ground and with an initial speed of 3 m/s. How long is the ball in the air before it lands on the ground? (Give your answer in seconds.)

Standing at the edge of a 70 meter high cliff, Failee throws a rock with a horizontal velocity of 21 m/s. How long is the rock in the air, and how far does it travel horizontally before striking the water ?

A diver runs off a platform with an initial horizontal velocity of 1.16 m/s in the positive x-direction. The platform is at a vertical height of 8.90 m above the water. How much time is the diver in the air before he strikes the water? O 1.77 s O 1.83 s O 3.21 s O 2.49 s O 1.35 s O 2.99 s

Two students are on a balcony 19.5 m above the street. One student throws a ball vertically downward at 16.6 m/s; at the same instant the other student throws a ball vertically upward at the same speed. The second ball just misses the balcony on the way down.  (a) What is the difference in their time in air? (b) What is the velocity of each ball as it strikes the ground?  (c) How far apart are the balls 0.900 s after they are thrown?

A juggler performs in a room whose ceiling is 4.62 m above the level of his hands. He throws a ball upward with an upward speed of v 0 so that it just reaches the ceiling. At the instant when the first ball is at ceiling, the juggler throws a second ball upward with 4v 0 /3 velocity. At what distance above the juggler’s hand do they pass each other?

A brick is thrown upward from the top of a building at an angle of 40° to the horizontal and with an initial speed of 17 m/s. If the brick is in flight for 2.5 s, how tall is the building?

From the edge of a high cliff overlooking a flat valley, you shoot a cannonball horizontally over the valley with an initial speed of 120 m/s. If the cliff is 400 m above the valley floor, how far does the cannonball travel in the horizontal direction before landing on the ground?

A juggler throws a bowling pin straight up with an initial speed of 7.4 m/s from an initial height of 3 m. How much time elapses until the bowling pin returns to the same initial height? (Do not round off the final answer)

An eagle is flying horizontally at 6.2m/a with a fish in its claws. It accidentally drops the fish. How much time passes before the fish’s speed doubles, and how much additional time would be required for the speed to double again?

Problem 1: A ball is initially 1.2 m above the ground. The ball is launched horizontally (0 = 0°) and the ball hits the ground after it travels a horizontal distance of 3.5 m. a) How long was the ball in the air? b) What was the initial speed of the ball?
