Question

a body of mass 20 kg is filled up to 10 M height calculate its potential energy if the body is allowed to fall find its potential energy just before it touches the ground

Answer 1

you know that energy is conserved everywhere.

so the maximum kinetic energy = maximum potential energy

so formula for potential energy= mgh

so m= 20kg

h=10m

g=9.8m/s^2

so, mgh = maximum potential energy= maximum kinetic energy = 20*10*9.8

so, maximum kinetic energy = 1960

hope you would understand

thank you

Answer 2

Answer:

Explanation:

you know that energy is conserved everywhere.

so the maximum kinetic energy = maximum potential energy

so formula for potential energy= mgh

so m= 20kg

h=10m

g=9.8m/s^2

so, mgh = maximum potential energy= maximum kinetic energy = 20*10*9.8

so, maximum kinetic energy = 1960
