Question

Find the value of H if it takes 49 j energy to move an object of mass 1 kg from the ground to a height of h​

Answer 1

Answer:

Potential energy mgh=1J(given)

h=

1×9.8

1

=0.102m

Answer 2

Explanation:

potential energy = mgh

m=1 kg

g= 9.8

, energy = 49 j

h=?

49 = 1×9.8× h

49= 9.8 × h

h = 49/9.8

h= 5
