What is acceleration?
a. change in velocity/change in time
b. change in distance/change in time
c. change in mass/change in volume
d. change in pressure/change in time

Most short-period comets do not have randomly oriented orbits because

Explain what it means to view something from a frame of reference. provide an example that illustrates your explanation. (4 points)

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 = ?
