Table 4 Measured average time of ball(s) passing the photogates 1( )elastic t (s) 2 ( )elastic t (s) 1( )inelastic t (s) 2( )inelastic t (s) (e) Use data in Tables 1 and 4 as well as Eqs. (4) and (7) to calculate the speed(s) of the ball(s) before and after elastic/inelastic collision. Record the results in Table 5. Table 5 Measured speed(s) of the ball(s) before and after elastic/inelastic collision 1 (m/s) 2 (m/s) 1( )in (m/s) (m/s) (f) Use Eqs. (1), (2), (6), and the data in Tables 1 and 5 to calculate the quantities listed in Tables 6 to 10.
