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.
