An elephant applies a force of 5000 N through a rope on a bundle of wood logs and moves them through a displacement of 250 m. The rope makes an angle of 28 degrees with the horizontal ground.

a. calculate the work done by the elephant in moving the load

b. If the elephant moved the load in a time of 1/2 hour, calculate the power output by the elephant in watts AND horsepower

work=F*d * cosTheta=5000*250*cos28

power(watts)=work/timeInSeconds
power(hp)=power(watts)/546
