Question

A block of mass 5 kg, which has an initial
speed of 3 m/s at time t = 0, slides on a
horizontal surface. Find the magnitude of the work that must be done on the block to bring it to rest.
Answer in units of J.
Negative work must be done ON the block, and the magnitude equals the initial kinetic energy, (M/2)*Vo^2
