Question

an object of mass 300 gram and work done of 50 joule what will be the height

Answer 1

W = mgh
W = 50 joule, m = 300g = 0.3kg & g=9.8 metre per second square.

$50joule = 0.3kg \times 9.8 \frac{m}{ {s}^{2} } \times h$

solving this we get h = 17m

where W= work done
m= mass
g= acceleration due to gravity
h = height
