Solution: A man throws a rock from a height of 10 m above the ground with an intial speed of 10 m/s at an angle of 30° above the horizontal. Use g = 10m/s2. [a] Find the maximum height above the man reached by the rock. [b] Find the time elapsed when it hits the ground. [c] Find the horizontal distance traveled by the rock to the point where it strikes the ground. [d] Find the magnitude of the velocity of the rock just as it strikes the ground.

Problem

A man throws a rock from a height of 10 m above the ground with an intial speed of 10 m/s at an angle of 30° above the horizontal. Use g = 10m/s2.

[a] Find the maximum height above the man reached by the rock.

[b] Find the time elapsed when it hits the ground.

[c] Find the horizontal distance traveled by the rock to the point where it strikes the ground.

[d] Find the magnitude of the velocity of the rock just as it strikes the ground.
