Answer:

The efficiency of the ramp is, Eff = 6.63 %

Explanation:

Given,

The work done by the person pushing the furniture up the ramp is, W₁ = 1240 J

The work done by the ramp is, W₀ = 822 J

The efficiency of the ramp is given by the formula,

Eff = ( W₀ / W₁ ) x 100%

= ( 822 / 12400 ) x 100%

= 6.63 %

Hence, the efficiency of the ramp is, Eff = 6.63 %
