the moon rotates once on its axis in 27.3 days. its radius is 1.74×106 m. compare this speed with the speed of a person at earth's equator due to earth's rotation.

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
