a)less work.b)The same amount of work.c)Twice as much workd)Four times as much worke)More than four times as much work?Justify your answer mathematically.
W = F*d W = mg*h (in this case) since linear relationship, it's a direct proportionality.. hence it requires double the work c)
Work done = Force x distance Both are raised same distance, and the Force worked against is the Weight of the car ( = m.g) so answer is (c)
