The famous motorbike artist evel knievel enjoys jumping. he departs from an inclined plane witha velocity of 100 km/h and no rotation. he wants to try a summersault while he is airborne within 2 s. based on the conservation of angular momentum, he will start to rotate if his wheels' rotation is slowed down. his wheels are hollow cylinders with a radius of 0.4 m and a mass of 10 kg. the inertia of the bike and him is 200 kgm2. calculate, how much the wheels' rotation has to be modified in order to make a full rotation of the bike during 2 s. let's assume the angular velocity can be changed within 0.1 s which angular acceleration does that correspond to?

Two manned satellites approaching one another at a relative speed of 0.550 m/s intend to dock. the first has a mass of 2.50 ✕ 103 kg, and the second a mass of 7.50 ✕ 103 kg. assume that the positive direction is directed from the second satellite towards the first satellite. (a) calculate the final velocity after docking, in the frame of reference in which the first satellite was originally at rest.(b) what is the loss of kinetic energy in this inelastic collision? (c) repeat both parts, in the frame of reference in which the second satellite was originally at rest. final velocity(d) loss of kinetic energy = ?
