Acart is loaded with a brick and pulled up at a constant speed along an inclined plane to the height of a seattop. if the mass of the loaded cart is 4.0 kg and the height of the seat top is 0.15 meters, then what is the potential energy of the loaded cart at the height of the seat top?

6 J

Explanation:

Gravitational Potential Energy can be calculated using the formula:

PE = mgh

where m is mass of object in kg

g is the gravitational acceleration of 10 m/s^2

h is the height at which object is thrown in m.

Hence, by substituting in the values, we get:

GPE = (4.0)(10)(0.15)

6 J

Hence, the potential energy is 6 J.
