Q. Two particles P and Q have speeds of 6m/s and 0m/s respectively. P directly collides with Q, the colision is perfectly elastic.

a) find the speed of Q directly after impact

b) find the impulse on Q

a)

so far i have worked out that using the law of conservation of momentum that

6 = X + 0.5Y

where x and y are the velocities of P and Q after the collision respectivly

however this is as far as i have got because to work out n e thing more i would need the coefficient of restitution

6 = E (X - Y)

b) would be easy given the velocity after :P
