What is true about impulse and momentum

momentum is the mass of a substance multiplied by the velocity while impulse is just the change of momentum

impulse deals with velocity while momentum deals with change in velocity

impulse is mass times velocity while momentum is force times time

momentum and impulse are unrelated to each other

A small car (mass = 71.25 kilograms), moving at 52.5 m/s, crashes head on with a 285 kilogram truck moving at 33.75 m/s in the opposite direction (negative velocity). If the two cars become intertwined and mangled (inelastic), with what velocity does the wreckage move? (Don't forget direction!)

a magnitude greater than 30 m/s moving in the initial direction of the truck

a magnitude lesser than 30m/s moving in the initial direction of the car

a magnitude lesser than 30 m/s moving in the initial direction of the car

a magnitude lesser than 30 m/s moving in the initial direction of the truck

A 0.2 kg red cue ball rolling at 1.4 m/s elastically collides directly with a 0.2 kg 9-Ball at rest.Which of the following is true?

the red cue ball would have a velocity of 0 m/s

the red cue ball would have a velocity greater than 1.0 m/s

the two cue balls would stick together and have the same velocity

the 9-ball would have a velocity greater than 0.5 m/s but less than 2m/s

the 9-ball would have a velocity greater than 2 m/s
