Question

A force is exerted in lifting a 100 kg mass straight up to the height of 10m. What is the amount of work? Explain your answer with a solution.

Answer 1

Answer:

W = F . d

= 100× 10

= 1000 is the answer

Answer 2

Answer:

Explanation:

Let the gravitational acceleration = g = $9.8 m/sec^2$

The force on 100 kg mass = F = 100*9.8 = 980 Newton

Work = Force * Displacement = 980*10 = 9800 Joule
