    6495.19 Joule

    Explanation:

    F = Weight of the crate = 250 N

    d = Distance the cart is pushed = 30 m

    θ = Angle of inclination = 60°

    The weight of the crate will be resloved into two components

    Fdsinθ and Fdcosθ

    Work done by the force of gravity is

    W = Fdsinθ

    ⇒W = 250*30*sin60

    ⇒W = 6495.19 Joule

    ∴ The work done by the force of gravity is 6495.19 Joule
