(a) What is the momentum in kg · m/s of a garbage truck that is 1.30 x 10 kg and is moving at 31.0 m/s? (Enter a number.) kg. m/s (b) At what speed in m/s would an 8.00 kg trash can have the same momentum as the truck? (Enter a number.) m/s A 0.700 kg hammer is moving horizontally at 9.00 m/s when it strikes a nail and comes to rest after driving it 1.00 cm into a board.
