A man pulls a trolley of mass 150 kg by the handle which is attached at 25 degrees over a distance of 50m. If the horizontal force applied is 1720 N calculate the Work done over this distance. What is the acceleration of the trolley?



Answer :

Answer:

The acceleration of the trolley is approximately 10.4m/s2.

Answer:

Explanation:

The angle is irrelevant because you're then given the horizontal force .

Work = force * distance

         = 1720 N * 50 m = 86000 j

Acceleration

  F = ma

  1720 N = 150 kg  * a

     a = 1720 / 150 = 11.5 m/s^2    ( neglecting friction)
