Question

THE WORK DONE IN LIFTING A MASS OF 1 KG TO A HEIGHT OF 9.8m IS

Answer 1

Explanation:

W = F. S

F = ma

= mg

= 1×10

= 10N

S = 9.8

W = F. S

= 9.8 × 10

= 98 J

Answer 2

Work done = P.E (POTENTIAL ENERGY) *please note that it is potential energy only for this case as there is height present*

P.E = mgh (where m is mass g is gravitational acceleration and h is height)

     = 1kg * 9.8 m/s^2 * 9.8 m

     =  96.04 Joules
