Unformatted text preview: nd the velocity and angle at which the ball was kicked, and determine the time of travel. Would the ball go over a 6ft goalie standing 15ft from the goal? 1 3. Problem 35 from Greenwood: Consider the free motion of an underdamped massspringdamper system such as that in Sec. 37. For each cycle of oscillation, what is the interval between the time of maximum velocity and the time at which the displacement is zero? 4. Problem 39 from Greenwood:A pendulum consists of a particle of mass m and a massless string of length 2R: As the de ection angle increases, the string wraps around one of two xed cylinders of radius R adjacent to the support point O: a Obtain the di erential equation for ; where is assumed to be positive. q b Assuming the initial conditions 0 = 0; _0 = 2gR ; nd max: 2...
