A 20 kg block is released from rest from the top of a ramp at point A at
a construction site as shown in the diagram. The ramp is inclined at an
angle of 30° to the horizontal and its top is at a height of 5 mabove the ground.
6.2 the kinetic frictional force between the 20kg block and the surface of the ramp is 30N. use energy principles to calculate the:
a. work done by the kinetic frictional force.
b. speed of the block at the point B at the bottom of the ramp
