A wedge with mass M rests on a fricitonsless horizontal table top. a block with mass m is placed on the wedge. There is no friction between the block and the wedge. The system is released from rest. q1: calculate the accelration of the wedge now why would the wedge have any accelration at all? wouldn't just stand still?.. I can't get how I'm suppose to calculate the acceleration of the wedge.
