Calculate the momentum change (Eq.2) during each collision and hence the average force given by: Favg = 7 ( 5 ) 7. Select one of the four collisions. Using the calculated average value of the spring constant calculate the spring force (collision force) in the time interval t, S t S t2 An easy way to do this is to copy the position vs time data during the collision time in an Excel file and then calculate the compression of the spring as a function of time. 8. Make a plot of the spring force as a function of time. What does the area under graph represent? Try to estimate the area under graph Questions Using your data investigate whether the collisions are elastic. In order to do so calculate the % of the initial kinetic energy lost in each of the four collisions. Collision Force collision ( 1) Fel = - K- DI = - 132.44. - 3 =397.32
