Aramp is used to load furniture onto a moving truck. the person does 1240 j of work pushing
the furniture up the ramp, and the ramp does 822 j of work. calculate the efficiency of the
ramp.

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 %

the maxium height is 34m/s
