A ball falls straight down onto a block that is wedge-shaped and is sitting on frictionless ice. The block is initially at rest (see the figure). Assuming the collision is perfectly elastic, is the total momentum of the block/ball system conserved? Is the total kinetic energy of the block/ball system exactly the same before and after the collision? Explain.
