Question

Calculate the work done, to take an object of mass 20kg to a height of 10m. (g= 9.8)​

Answer 1

Explanation:

Given : Mass of the object = m = 20 kg. Height to which the object is raised = 10 = h metres. Acceleration due to gravity = g = 10 m/s²

To find : Work done = m×g×h (potential energy) Work done = 20×10×10. Work done = 200×10. Work done = 2000 joules.
