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 h frictionless plane rough surface H=0.4

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 k 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? T 4 h frictionless plane rough surface H=0.4
