PROJECTILE MOTION WORKSHEET

1. A ball is kicked horizontally at 8.0 m/s from a cliff 80m high. How far from the base of the cliff

will the stone strike the ground?

2. How long will it take a shell fired from a cliff at an initial velocity of 800 m/s at an angle 30°

below the horizontal to reach the ground 150m below?

3. Jason Kendall throws a baseball with a horizontal component of velocity of 25 m/s. It takes 3.00s

to come back to its original height. Calculate its horizontal range, its initial vertical component of

velocity and its initial angle of projection.

4. An egg is thrown horizontally off the roof of SI, which is 60 meters high, with an initial velocity

of 6.5 m/s. How long does it take to hit the ground? How far does it go in the x direction?

5. A diver jumps UP off a pier at an angle of 25o with an initial velocity of 3.2 m/s. How far from

the pier will the diver hit the water (Assume the level of water is the same as the pier)

6. Wile E. Coyote is holding a “HEAVY DUTY ACMETM ANVIL” on a cliff that is 40.0 meters

high. The Roadrunner (beep-beep), who is 1.0 meter tall, is running on a road toward the cliff at a

constant velocity of 10.0 m/s. Wile E. Coyote wants to drop the anvil on the Roadrunner’s head.

How far away should the Roadrunner be when Wile E. drops the anvil?

7. A bullet is fired at an angle of 60o with an initial velocity of 200.0 m/s. How long is the bullet in

the air? What is the maximum height reached by the bullet?

8. A bullet is fired at an angle of 45o. Neglecting air resistance, what is the direction of acceleration

during the flight of the bullet?

a) upward c) dependent on the initial velocity

b) downward d) at a 45o angle

9. A golfer drives her golf ball from the tee down the fairway in a high arcing shot. When the ball is

at the highest point of its flight:

a. the velocity and acceleration are both zero

b. the x-velocity is zero and the y-velocity is zero

c. the x-velocity is non-zero, but the y-velocity is zero

d. the velocity is non-zero, but the acceleration is zero

10. A bullet is fired horizontally from a gun. At the same time a similar bullet is dropped from the

same height. The fired bullet will:

a) hit the ground first c) hit at the same time as the dropped bullet

b) hit the ground second d) never hit the ground
