Acart at the top of a 300m hill has a mass of 40kg. what is the carts gravitational potential energy?

The cart gravitational potential energy is 117,600 Joule

Step-by-step explanation:

First lets define what a gravitational potential energy is.

A gravitational potential energy is the energy stored in an object that rise above a certain height surface.

The formula for calculating the gravitational potential energy(P.E) is m×g×h, where m is the mass of the object measured in kilograms(kg), g is the acceleration due to gravity measured in *(m/s²). It is a constant and always equal to 9.8 m/s²   on the earth surface and h is the height of the object above the surface in (m).

The gravitational potential energy is measured in Joules(J).

From the question, mass(m) is given as 40 kg  and the height(h) is 300m

and g=9.8m/s²

Gravitational Potential Energy(P.E) = m×g×h

                                                          =40 ×9.8 ×300

                                                          =117,600 Joules.

Therefore the cart gravitational potential energy is 117,600 Joules.

worked it out i believe

i would be happy to . most people on would also love to i'm sure. if you just want someone who has done algebra before and want a little more personal relationship than just begging strangers for , i can certainly be of service. i do have college myself so i might not be 24/7.
