Question

work done, W = mgh =
A Example 9. Calculate the energy possessed by a stone of mass 10g kept at a height
of 5m. [Given g = 9.8 ms-2]
Given, m = 10g = 10 x 10-kg; h = 5m ; g = 9.8 ms-2
Solution​

Answer 1

Answer:

0.49 J

Step-by-step explanation:

Mass(m)= 10 g = 0.01 kg. [ mass has to be changed to its S.I. unit]

Acc. due to gravity(g)= 9.8 m/s.

Height(h)= 5 m.

Work done = m*g*h = (0.01* 9.8* 5) J = 0.49 J.

Answer 2

answer:-(490kgm-2s-2)

explanation:-(5×10×9.8)=490
