A3500 w motor does 8000 j of work when it lifts a rhinoceros 30.0 m. how long did this take?

The answer is 2.28 seconds

Explanation:

Given data:

Work done = 8000J

Distance , d = 30 m

Power , P =3500 W

We know that

(a)  Work done = force × distance

      8000 J    = F x 30 m

                 F   = 8000 J / 30 m

                   =  266 N

(b) Power = work done / time taken

      3500 W = 8000 J/ time taken  

       3500 W x time taken = 8000 J  

         Time taken = 8000 J / 3500 W =2.28 s
