In order to catch Ronan by surprise, Groot throws Rocket (8.50 kg) at an angle of 30.0° above the horizontal. If Groot’s arm moves through a horizontal distance of 1.75 m in the process of applying the force at the given angle, a. How much work does Groot do on Rocket if he uses a force of 1200. N to throw him? b. What speed does Rocket reach if he started from rest and the total work was created by Groot alone? c. What would be Rocket’s total range if he followed a parabolic path after release, ending at the same height from which he was thrown?
