Efficiency = (Work done / Energy input) × 100% = (4900 J / 5000 J) × 100% = 98%

W = F × s = 20 N × 3 m = 60 J

Efficiency = (Work done / Energy input) × 100% Efficiency = (Work done / Energy input) ×

A 20 N force is applied to a block, causing it to move 3 m to the right. Calculate the work done on the block. Efficiency = (Work done / Energy input) ×

Work done = m × g × h = 100 kg × 9.8 m/s^2 × 5 m = 4900 J Efficiency = (Work done / Energy input) ×
