A kid pushes a sled on ice that is smooth, level and essentially frictionless. The kid is 50kg, the sled is 10kg, he pushes the sled hard enough to give it a veloctity of 5m/s. How fast does he end up moving backwards on the ice when letting go of the sled?
The Attempt at a Solution
I did p=mv to find the sleds momentum which is p=(10)(5) for a total of 50m/s. Due to law of conservation of Momentum the boy will have the same momentum correct? Thus leaving me with finding the boys momentum as 50=(50)v and his velocity being 1m/s? Thanks in advance![/B]
