3. A block of mass 1.0 kg collides with a horizontally oriented "massless" spring that has a force constant of k = 400 N/m. [4 pt] a. Assuming the horizontal

surface to be frictionless, calculate the maximum compression of the spring if the block is moving at 2.0 m/s. b. Assuming the kinetic coefficient of friction between the surface and the block is 0.50 and the speed of the block is 2.0 m/s at the moment the block collides with the spring,calculate the maximum compression of the spring
