Momentum + coefficient of restitution this is driving me nuts!
A Mass of 2kg traveling at 2m/s is struck by a mass of 4 kg traveling at 3m/s. If the coefficient of restitution for the two materials is 0.4 calculate their final velocities.
M1U1+M2U2=M1V1+M2V2
E=V2-V1/U2-U1
From what i know, the best way to do it is use both equations and create two simultaneous equations?
Is this correct? i seem to end up with V2=-1.2 however I am pretty sure this is wrong.
any help would be great.
