4. A block of mass m is connected to a spring of spring constant k and is initially at the top of a frictionless hemisphere of radius R. The block is given a slight nudge and slides down the hemisphere. Using work-kinetic energy methods, find the maximum velocity of the block. {Your answer may be in terms of 0, g, k, R and m}
