Two hoists raise separate flood barriers vertically. Each hoist exerts a constant upward force while its barrier moves upwards.
Hoist A exerts an upward force of 2400 N and raises its barrier through a vertical distance of 1.8 m.
Calculate the work done by hoist A.
Hoist B exerts an upward force of 1800 N and does the same amount of work as hoist A.
Calculate the vertical distance through which hoist B raises its barrier.
