Question 1161284: What is the minimum work needed to push a 950-Kg car 710 m up along a 9 degrees incline? Ignore friction.
A) W = 1000000 J W) V = 0 J C) W = 1.33J D) W = 674500 J Answer by ikleyn(52817) (Show Source):
Minimum work, in this case, is the product of the weight of the car, W = 950 kg * 9.81 m'/s^2, by the height 710 m
minimum work = 950*9.81*710 = 6616845 J (joules). ANSWER
It DOES NOT DEPEND on the slope of incline.
