ANSWER ASAP 4) Kanye West is pushing a shopping cart (total mass 145.0 kg) at a velocity of 4.65 m/s. All of a
sudden 35.0 kg of "Kanye for President" signs fall into the cart. How fast is he traveling now?

5) A cue ball .17 kg travels at 2.16 m/s it hits an eight ball .156 kg which is initially at rest after the collision the cue ball continues forward at .963 m/s how fast is the eight ball traveling?

6) A 2400 kg truck traveling at 27.45 m/s has a head on collision with a 1300 kg car traveling at 37.54 m/s they collide and stick together what is the final velocity?

Amerry-go-round of radius r, shown in the figure, is rotating at constant angular speed. the friction in its bearings is so small that it can be ignored. a sandbag of mass m is dropped onto the merry-go-round, at a position designated by r. the sandbag does not slip or roll upon contact with the merry-go-round. how would you rank the following different combinations of m and r on the basis of the angular speed of the merry-go-round after the sandbag "sticks" to the merry-go-round from largest to smallest. a) m = 10kg, r = 0.25r b) m = 20kg, r = 0.25r c) m = 10kg, r = 0.50r d) m = 10kg, r = 1.0r e) m = 15kg, r = 0.75r f) m = 40kg, r = 0.25r
