need help in may june 2009
http://www.xtremepapers.com/papers/...and AS Level/Physics (9702)/9702_s09_qp_2.pdf
Q2 d)...
the mark scheme says
(d) either
speed of approach = 4.0 m s-1 and speed of separation = 2.4 m s-1 .............................................. M1 not equal and so inelastic ....................................................... A1
or kinetic energy before = 9.6 J and kinetic energy after collision = 4.99 J ...................................... M1 kinetic energy after is less / not conserved so inelastic .......... A1
how can i get the kinetic energy after collision and what does speed of approach and speed of separation..first time to hear that in phys :O:O
