Assignment Help Physics
##### Reference no: EM13242876

A man stands on the roof of a building of height 16.8m and throws a rock with a velocity of magnitude 31.8m/s at an angle of 25.0? above the horizontal. You can ignore air resistance.

part A: Calculate the maximum height above the roof reached by the rock. I was able to find this which was 9.21 m

part B: Calculate the magnitude of the velocity of the rock just before it strikes the ground?

part C: Calculate the horizontal distance from the base of the building to the point where the rock strikes the ground.
