A pulley system conisisting of three pulleys is used to lift a pallet
of
bricks Weighing 600N
through a height of 40m. The
force required to lift the pallet
at a
steady speed is 210N and the rope is pulled through a distance of 120m

(a) Neglecting
the mass
of the pulleys and rope, calculate the useful work
done in lifting the pallet. ​
