Question

you do 185 j of work pulling a cart up a ramp. if the ramp does 153 j of work what is the efficient of the ram

Answer 1

Efficiency of the ram is calculated by dividing the work done by the work or energy that is exerted to do so. This is calculated through the equation,

S = ((Wout) / (Win)) x 100%

Substiuting the known values to the equation.

S = (153 J)/(185 J) x 100%

Efficiency = 82.7%.
