Assume that a team of engineers runs a friction test on the car and track. The team finds that the car loses 210 joules of energy over each meter of track. How much energy does the roller coaster lose from friction as it travels from the top of the first hill to the top of the second hill

Respuesta :

The rate of energy loss from friction is 210 joules/meter of track. Multiply by the length of the track (320 meters) to find the total energy lost:

210 J/m × 320 m = 67,200 J

The roller coaster car loses 67,200 joules of energy as heat between the tops of the two hills.
