Question 71
Easy

A window-cleaning robot has a mass of 5.2 kg.

The robot climbs vertically up a skyscraper window to a height of 14 m.

Calculate the increase in gravitational potential energy of the robot.

Use the equation:

gravitational potential energy=mass×gravitational field strength×height \text{gravitational potential energy} = \text{mass} \times \text{gravitational field strength} \times \text{height} gravitational potential energy=mass×gravitational field strength×height

Gravitational field strength, g=10 N/kgg = 10\ \text{N/kg}g=10 N/kg.
