Hello! I have here an interesting problem: Body A, which has a mass m, is sliding on a frictionless horizontal surface, and is approaching a block of ice that has a height of H=2m. What is the minimal speed of the body so that it can slide over the ice block? There is also no friction btw the ice block and the surface, nor btw the ice block & the body. P.S. I would have uploaded the picture that goes with the problem, if I just knew how.. Can someone help? :-)

if the block of ice is a parallelopipe then its volume can be found out. density of ice can be known. then the mass of the block is known and hence its weight.then try.
