Help please
A wad of putty (mass 0.4 kg) strikes a stationary box
(mass 2.00 kg) and sticks to it. The velocity of the
putty right before it strikes the box is 20.0 m/s. They
end up moving together for a distance of 0.5 m
before coming to rest.
(a) What type of collision is this? Inelastic
(b) What is the combined velocity of the putty and
box right after collision? 4.2 m/s
(c) What is the force of friction acting over the 0.5 m
distance? 41 N
