Problem: A man stands on the roof of a 10.0m -tall building and throws a rock with a velocity of magnitude 24.0m/s at an angle of 34.0 degree above the horizontal. You can ignore air resistance.
Part A: Calculate the horizontal distance from the base of the building to the point where the rock strikes the ground.
Please show all intermediate steps and formulas for above problem.
