Question 48

A window-cleaning robot has a mass of 6.0 kg.

The robot climbs vertically up the side of a glass building to a height of 15 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=9.8 N/kgg = 9.8\text{ N/kg}g=9.8 N/kg.
