1.	A particle of mass m moving with velocity v_(0) strikes a smooth wedge of mass M. After collision the ball satrts up moving an inclined plane and raises to height 'h'. Then :
Answer» Particle is at REST w.r.t. GROUND Both particle and wedge are at rest w.r.t. ground As it MOVES up, K.E. of centre of mass doesn't remain constant All the above are TRUE Answer :C
