Question

(1)
Q6. A hammer of mass 5kg is lifted to a height of 1m . Find potential energy of the hammer if acceleration due to
gravity has its standard value.

​

Answer 1

49j

Explanation:

earths gravity due to accleration =9.8. p=mgh p=5×9.8×1=49

Answer 2

Answer:

I hope you will understand...

Explanation:

Given, mass = 5kg

height = 1m

acceleration due to gravity (g) = 9.8m/s²

Now using , P.E. = mgh

= 5*9.8*1

= 5*98/10*1

= 49J
