    Calculating Min Work for 800kg Car on 9.0° Incline

    That's all the information that was given to me... I know I'm supposed to find force by multiplying the mass and gravity...but i think the number I'm getting after i put it into the work formula is too big...

    Calculating Min Work for 800kg Car on 9.0° Incline

    I have been trying this problem multiple times but it still says I'm wrong: What is the minimum work needed to push a 800 kg car 930 m up along a 9.0^\circ incline? i'm using the formula: W= Fdcos(theta) F= mg what am i doing wrong?
