Please help. Thank you!

Part A A man stands on the roof of a 12.0-m-tall building and throws a rock with a velocity of magnitude 30.0 m /s at an angle of 41.0 above the horizontal. You Calculate the maximum height above the roof reached by the rock. can ignore air resistance. Assume that the rock is thrown from the level of the roof. Express your answer with the appropriate units. HA hmax = Value Units Submit Request Answer Part B Calculate the magnitude of the velocity of the rock just before it strikes the ground. Express your answer with the appropriate units. HA U = Value Units Submit Request Answer Part C Calculate the horizontal distance from the base of the building to the point where the rock strikes the ground. Express your answer with the appropriate units. ? d = Value Units
