important aspects. m spring stretched for Use an angle between 15 and 20 degrees for this entire experiment Q1. To think about the energy in the Nittany bouncer, where is the kinetic energy, and gravitational and spring potential energy maximum and minimum along the track? Please use the motion sensor as the zero point of gravitational potential energy and the spring at its relaxed length (x = x ) as the zero point of elastic potential energy. (Use max/min or zero, or blank) K Ug Us Top X =XO Bottom Q2. Because of dissipative forces (friction) the car will come to rest at some place along the track. We call this the equilibrium point. What can you say about the net force on the car here
