An electric motor moves a chain that pulls the roller coaster car 180 meters to the top of the first hill. the chain exerts a force of 2,524 newtons on the car. how much kinetic energy does the car gain from the work done on it? use the formula change in ke = f × d.

Explanation:

The work done on an object is equal to its change in kinetic energy: Change in KE = F × d.

Plug the values for F and d into the formula and solve:

Change in KE=2,524 × 180

=454,320 joules

The roller coaster gains 454,320 joules of energy from the work done on it by the chain.
