Question

If the mass of the body is 20 kg .if it is moving with the speed of 10 m/s . What is its kinetic energy?

Answer 1

Answer:

1000 joules

Explanation:

kinetic energy=½mv²

given:m=20kg

v=10m/s

kinetic energy=½×20×(10)²

=½×20×100

=½×2000

=2000/2

=1000 joules

kinetic energy=1000joules

Answer 2

Answer:
