Question

A crane lifts a 200-kilogram weight to a height of 50 meters. What would the gravitational potential energy be?

A) 100 joules
B) 1,000 joules
C) 5,000 joules
D) 10,000 joules

Answer 1

The gravitational potential energy of a 200-kilogram weight lifted to a height of 50 meters is 98,000 joules.

Step-by-step explanation:

The gravitational potential energy of an object can be calculated using the formula:

Potential Energy = mass × gravity × height

In this case, the mass is 200 kilograms, gravity is 9.8 m/s², and the height is 50 meters. Plugging in these values into the formula:

Potential Energy = 200 kg × 9.8 m/s² × 50 m = 98,000 joules

Therefore, the gravitational potential energy would be 98,000 joules.
