A block of mass 5M is attached to a very light horizontal spring of force constant k= 100 N and is resting on a frictionless horizontal table. Suddenly it is struck by a stone of mass M traveling horizontally at speed Vo =33 m/s to the right, after which the stone rebounds with speed v/3 horizontally to the left. What is the speed ( in m/s) of the block of mass 5M after the collision (before the spring is compressed)? 5M ww Answer:

Answer:
A solid cylinder (inder
MR) rolls without slipping down an inclined plane from rest as shown in the figure. It has mass M and
radius R. What is its linear acceleration (in m/s) after travelling a distance of 10 m down the inclined plane with e 40.2?
