Question

An electric motor lifts a roller coaster car that weighs 10,000 N to the top of the first hill that is 20 m above the ground. To add suspense, the ride up to the top takes 150 seconds.

Calculate the work done by the motor.

Answer 1

Step-by-step explanation:

Work = F * d

= 10000 N * 20 m = 200 000 J

Time to top is not needed unless you want to calculate POWER watts
