... The World Solar Challenge in 1987 was the first car race in which all the vehicles were solar powered. The winner was the GM Sunraycer, which had a mass of 177.4 kg, not counting the driver’s mass. Assume that the driver had a mass of 61.5 kg, so that the total momentum of the car and driver had a m ...

... The bag A, having a mass of 6 kg, is released from rest at the position q = 0o. After falling to q = 90o, it strikes an 18 kg box B. If the coefficient of restitution between the bag and box is e = 0.5, determine (i) the velocities of the bag and box just after impact (ii) the loss of energy during ...
