Acat with a mass of 4.50 kilograms sits on a ledge 0.800 meters above the ground. what is the potential energy of the cat? 346 j 35.3 j 3.60 j 0.350 j

The correct answer to the question is 35.3 J.

CALCULATION:

The mass of the car is given as m = 4.50 kg.

The cat is 0.800 m above the ground.

Hence, height of ledge from ground h = 0.800 m.

We are asked to calculate the potential energy of the body.

The potential energy possessed by the cat at a height h is nothing else than gravitational potential energy.

The gravitational potential energy of a body at a height h is calculated as-

                         Potential energy P.E = mgh.

Here, g is the acceleration due to gravity. Its value is

Hence, the potential energy of the cat is calculated as -

                                         P.E = mgh

                                                =

                                                =  35.28 J

                                                = 35.3 J                         [ANS]
