GPE = m × g × h = 10 kg × 9.8 m/s^2 × 4 m = 392 J

KE = ½ × m × v^2 = ½ × 5 kg × (2 m/s)^2 = 10 J GPE = m × g × h = 10 kg × 9

A 50 N force is applied to a block, causing it to move 2 m to the right. Calculate the work done on the block. If the machine takes 5 seconds to lift

First, calculate the work done:

A machine requires an input energy of 2000 J to lift a 50 kg load to a height of 2 m. If the machine takes 5 seconds to lift the load, calculate its efficiency. GPE = m × g × h = 10 kg × 9

A 10 kg object is lifted to a height of 4 m above the ground. Calculate its gravitational potential energy.
