Question

an object of mass 2 kg is lifted up to hight 2m the work done will be

Answer 1

Answer:

Hi. .

Work= mass * g* h

Thus W= 2 * 10 * 2

W= 40 J..

Hope this helps u!!

Answer 2

Let us calculate the work done in lifting an object of mass m through a height h, such as in Figure 1. If the object is lifted straight up at constant speed, then the force needed to lift it is equal to its weight mg. The work done on the mass is then W = Fd = mgh.
