A500-n weight sits on the small piston of a hydraulic machine. the small piston has an area of 2.0 cm2. if the large piston has an area of 40 cm2, assume the pistons each have negligible weight

(a) how much weight can the large piston support?
(b) find the pressure applied to the pistons.

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 = ?
