9. An object with mass m = 2 kg is released from rest at a height h = 6 m from the top of
an inclined plane. It slides down the inclined plane without friction then slides across a
rough surface with a coefficient of kinetic friction u, = 0.4. (a) What is the speed of the
object after it slides 4 meters across the rough surface? (b) How much work is done by
friction over this distance?
