PLEASE HELP :D! DUE SOON!! A ball weighing .05 kg strikes a 1000 kg
stationary wall at 30 m/s. According to Newton's Third Law, which of these must be true?

A: The wall moves away from the ball at 30 m/s

B: The total Momentum of the system before impact was 1.5 kg • m/s

C: The total Momentum of the system before impact was 15 kg • m/s

D: The total Momentum of the system after impact is 30000 kg • m/s

​

Which accounts for an increase in the temperature of a gas that is kept a constant volume

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 = ?

Contains chemical energy. a. heat b. light c. natural gas
