Explanation:
Efficiency of ramp is given by
Where n is the efficiency, W is work and subscripts o and i represent output and input respectively.
The work input is what the workers do and that is given as 15 kJ
The work output
Since work is product of force and perpendicular distance and substituting force with 3500 N and distance with 4 m we get that the work output is 3500*4=14000 J= 14 kJ
Finally, substituting 14 kJ and 15 kJ for work output and input respectively we deduce that
