A1500-kg car is travelling at a constant speed of 10 m/s in a circular path. what fact would support a claim that there was a net force on the car? a) the car was moving at 10 m/s. b) the car is moving at constant speed. c) the car is moving in a circular path. d) the car has a mass of 1500 kilograms.

work: w = fd (given)

work done by chet   =50*1 = 50 j

work done by mika =40*2 = 80 j

work done by sara =30*1.5 = 45 j

work done by bill =60*0.5 = 30 j

students in order from the greatest amount of work done to the least is mika> chet> sara> bill

hence option (b) is correct.

hello there!

your answer is a “generator”

a generator does not create energy but instead it transforms it.

it’s basically a motor working in reverse.
