What is the minimum work needed

Reference no: EM13689081

Here is the question which I am struggling on, please help me!

Question: What is the minimum work needed to push a 900kg car 930m up along a 8.0 degree incline? Assume the effective coefficient of friction retarding the car is 0.22.

If possible just a brief explanation how you got the answer and express your answer using two significant figures?
