How can we increase the gravitational potential energy of the car? a) strap a boulder to the car so that it weighs more. b) keep the length of the hill at 50 m but only 5 m tall. c) take the interior out of the car so that the car has less mass. d) keep the hill at 10 m tall but increase the length of the hill so that the car has farther to roll.

The correct answer is option A which is Strap a boulder to the car so that it weighs more.

The gravitational potential energy of an object can be described as the energy due to the position of the car.

It usually depends upon the height of the car from the ground and its weight.

Higher the weight more the gravitational potential energy as well as higher the distance between the car and earth surface more the potential energy.

Gravitational potential energy = mgh

Hence here the correct statement about increasing the gravitational potential energy is option A.

answer: national resource conservation services

national resource conservation services is the us. based approach that provides technical and financial assistance for natural resource management. nrcs society in conservation of resources by involving in activities like farmland protection, flood prevention, watershed protection, urban conservation, conserves economic and environmental conditions. it conducts soil surveys and implements the policy of natural resources management on the society.
