Answer:

Explanation: Work=force×distance

W=F×S  where W=10,000J,  F=m×g=225 kg×10 N/kg= 2250 N

⇒S=W/F

     = 10000/2250

     = 4.44 m

The box will be raised 4.53 m

What is work done ?

Work done is defined as the product of component of the force in the direction of the displacement and the magnitude of  this displacement .

Work done = F .s = Fs cos (theta)

F = mg

s =h

theta = 0°

cos (theta) = cos 0 = 1

hence , work done = m*g*h

Potential energy is stored in the form of work done

potential energy = work done to raise the box = m*g*h

given

mass (m) = 225kg

work done(WD) = 10,000 J

height (h) = ?

potential energy = m*g*h

10,000 J= 225kg * 9.8m/s^2 * h

h = 4.53 m

The box will be raised 4.53 m
