    Solve Collision Problem: 1300kg Car A vs 1200kg Car B

    A 1300kg car A stikes a parked 1200kg car B. Car B slides 2m after impact. The coefficient of friction between B's tires and the road is u=0.8. The coefficient of restitution is e=0.4. What is the velocity of A just before impact? I have the equations: mA*vA + mB*vB = mAvA' + mBvB' e =...

    Finding the Angle of Release for a Pellet on Top of a Cylinder

    I need a little help with this problem. There is a small 0.2kg pellet sitting on the top of a cylinder of radius 0.8m. What is the value of the angle at which the pellet loses contact with the surface of the cylinder? I just need a little help on how to get started with this one. I was...
