Hills and Projectiles
1) Shoot a red plastic rocket from the window of your physics
classroom, 5.00 m above the ground. If the rocket is launched 20.0º above
horizontal at 33.0 m/s, how high will it go?
2) You’re standing on top of a cliff 25.0 m high. You throw a
baseball at 15.0 m/s, 40.0º above horizontal. How high will it go? How far will
it move horizontally?
3) A football is kicked from level ground at 28.0 m/s, 40.0º
above the horizontal. How high will it go? When will the ball be 1.50 m above
the ground?
4) Stand on a roof 12.0 m high. Throw a stone at 8.50 m/s, 25.0º
below (not above) horizontal. How far will the stone move horizontally?
5) A golfer hits a ball from a tee 7.50 m lower than the place
where the ball will land. The ball leaves the tee at 42.0 m/s, 30.0º above the
horizontal. How far does the ball travel horizontally?
