B) The work done in moving the mass is given by the equation: W = Fd, where W is the work done, F is the force applied and d is the distance
over which the force has been applied.
If the mass is increased to 30kg, the angle becomes 40°, the coefficient of
friction remains at 0.4, and the acceleration becomes 2ms 2, and the block
moves a distance of 6 metres up the ramp, calculate, in one chained calculation, the
work done.
