A conveyor belt, located 2.10 m above ground, shoots out rock at a speed of 11.0 m/s at an angle of 16°above the horizontal. The rocks fly off the conveyor belt, and land on the ground some distance away. (a) What is the minimum speed of a rock during its flight? (b) What is the horizontal distance away from the conveyor belt that the rocks would land on the ground? (c) You have a 2.00 m high portable barrier that you are asked to position in such a way that it blocks the rocks' flight. What is the smallest horizontal distance away from the conveyor belt that you can position the barrier?

A conveyor belt, located 2.10 m above ground, shoots out rock at a speed of 11.0 m/s at an angle of
16°above the horizontal. The rocks fly off the conveyor belt, and land on the ground some distance away.
(a) What is the minimum speed of a rock during its flight? (b) What is the horizontal distance away from
the conveyor belt that the rocks would land on the ground? (c) You have a 2.00 m high portable barrier
that you are asked to position in such a way that it blocks the rocks' flight. What is the smallest horizontal
distance away from the conveyor belt that you can position the barrier?
