A 1000-kg car and a 2000-kg car are hoisted the same distance. Raising the more massive car requires?

a) less work. b) as much work. c) twice as much work. d) four times as much work. e) more than four times as much work. 10 points will be given to correct answer tonight!

c is the solution.

Same as last question: W=f*d f (force) is 1000Kg and 2000Kg (actually it's mass but you can use it as force, or weight, in this case) so doubling force doubles work: 2W=2f*d c)
