Suppose I throw a rock horizontally with an initial speed of 30 m/s. Suppose my release point is 2 m above the ground. (a) How long does it take for the rock to hit the ground? (b) How far in the horizontal direction does the rock travel? (c) What is the speed of the rock right before it hits the ground?

A stone is thrown with an initial speed of 20 m/s at an angle of 35° above the horizontal from the top of a 53 m building. What is the speed of the rock as it strikes the ground (ignore air resistance).

While standing on the roof of a building, a boy throws a tennis ball with an initial speed of 15 m / s at an angle of 35 ° below the horizontal. The ball lands on the ground 2.8 s later. How tall, in meters, is the building?

A student stands at the edge of a cliff and throws a stone horizontally over the edge with a speed of 17.0 m/s. The cliff is h = 51.0 m above a flat horizontal beach, as shown in the figure below. How long after being released does the stone strike the beach below the cliff? (s) With what speed and angle of impact does the stone land?      ( m/s)      ( ° below the horizontal)

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?

You are playing Hot Rod toy cars with your nephew and niece. Your nephew wanted to show off how fast he could launch a Hot Rod off the dining table 1.00 m above the floor by thrusting the car forward very fast but was no match against your niece who compensated slight lack of speed by pushing the car straight forward reaching a speed of 4.5 m/s at the edge of the table top when she let go of it. What was the magnitude of the final speed when it hit the floor?

When throwing a ball, your hand releases it at a height of 1.5 m above the ground with velocity 6.8 m/s in direction 57° above the horizontal. (a) How high above the ground (not your hand) does the ball go?(b) At the highest point, how far is the ball horizontally from the point of release?

A baseball is thrown with an initial speed of 37.5 m/s at a 42.0° angle in the absence of air resistance. a) What is the maximum height reached by the baseball? b) What is the magnitude and direction of the baseball's velocity at t = 2.50 s? c) What is the ball's height when it has traveled a horizontal distance of 55.0 m?

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 Supply plane needs to drop a package of food to scientists working on a glacier in Greenland.  The plane flies 97 m above the glacier at a speed of 133 m/s.  How far away from the target should it drop the package? (Hint: This is a horizontal projectile. The package has the same initial speed as the plane)
