Question

find total energy of body of mass 5kg height 10m from the ground falling straight velocity 20m/s accleration due to gravity 10m/s

Answer 1

Answer:

not getting perfect answer

Answer 2

Answer:

Total energy of body is 1500 J

Explanation:

Total energy of freely falling body is sum of the kinetic energy and potential energy

here m=5 kg

h=10 m

v=20 m/s

g=10 m/s^2

total energy is

$TE=KE+PE\\TE=\frac{1}{2} mv^2 +mgh\\TE=\frac{1}{2} 5\times20^2 +5\times 10\times 10\\TE=1500 J$
