A simple pendulum suspended in a rocket ship has a period T0. Assume that the rocket ship is near the earth in a uniform gravitational field. a. If the ship moves upward with a constant velocity, the period increases. a. True. b. False. b. If the length of the pendulum is doubled, the new period will be: square root of 2 times T0. a. True.
b. False. c. If the mass of the pendulum doubles, the period increases. a. True.
b. False. d. If the ship accelerates downward at 9.81 m/s2, the pendulum will no longer oscillate. a. True.
b. False. e. If the ship accelerates upward, the period increases. a. True.
b. False.

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 = ?
