Question

What is the minimum work needed to push a 850 -kgkg car 750 mm up along a 9.5 ∘∘ incline? Ignore friction.

Express your answer to two significant figures and include the appropriate units.

Answer 1

Work = Force * Displacement

F = MgSin(theta )

W = Mg Sin (theta) * 750 J

Plug in M= 850 Kg,

Sintheta = Sin 9.5

W =1416834.6 J
