Question

Work done of a body of mass 10 kg to lift it through certain height is 490 j. calculate the height through which the body is lifted?

Answer 1

Hi friend!

Work done on body to lift
 = mgh

=>490
 
h = 490/98m

which gives us: 5m as the answer.

Answer 2

Hey there !!

Mass = m = 10kg

Height = h




g = 9.8 m/s²


Potential Energy = mgh = 490 J

10 × 9.8 × h = 490

98 h = 490

h = 490 / 98
= 5 metre

Hope this Helps You !!
