A 6.00 Kg mass initially at rest slides down a ramp which makes
an angle of with horizontal at a
height of 5.0 m above the bottom of the slide and hits a 10.00 Kg
mass which is at rest, after collision, the 6.00 Kg mass bounces
back with a velocity of 0.60 m/s and 10.0 kg mass slides forward on
level. If the coefficient of kinetic friction for the incline is
0.30 and level is...
