This problem involves both rotational kinematics and 2D projectile motion. A catapult is a medieval siege engine which uses an arm to hurl projectiles at a great distance. The particular catapult shown in the figure below, has an arm 5 m long attached by ropes to a large wooden bow that will make the arm move along a circular path when the catapult is released. Assume the catapult’s arm starts in an horizontal position and is accelerated uniformely for 0.25 s to reach a position 60° above the horizontal, at which point a 20 kg rock is released. Calculate the minimum and maximum distance from the release point, this catapult can be placed in order to throw the rock above a 10 m wall
