consists of a k and a catch for the spring made to project the object. When a ball is loaded into the tube, is compresses the s 11.5 om. If you shoot a ping pong com nest up, how wa ?IThe gravitational potential go? energy before it is shot is negigible). mass of ball the below one story 4 and Spiderman contains a mass of about 75 kg. He begins his motion from rest, speed does he contain at point x? twelve Story Bulding Two Stories of Space Between Spiderman and the Ground

Solution

The potential enegy store in compressed spring = kx^2 /2 = 18.0 * (0.115) ^2 / 2 = 0.119 Joules

when the ball reaches maxiumum height , all the potential energy of the spring is converted to gravitational potential energy of the ball

                                          kx^2 / 2 = mgh

                                                     h = 0.119 / m * g              m is the mass of the ball = 0.05,

                                                                                    a acceleration due to gravity 9.8m/s2

                                                           = 0.242 m or 24.2 cms
