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.

think about the oscillation of the toy shown in the video. when the toy is at the highest point of its motion, its velocity is zero and its acceleration is negative.

with the invention of the automobile, the woman of the house could drive to the store and get groceries. women were also free to socialize more. during world war ii women were allowed to work in factories to the war effort and could drive to work or ride mass transit buses to their jobs.
