Question

Calculate the work done to take an object of mass 20 kg to a height of 10 M 9 is equal to 9.8 metre per second square

Answer 1

answer : kilojoules.

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 = mxgxh (potential energy) Work done = 20x10x10. Work done = 200x10. Work done = 2000 joules.
