Question

And object has a velocity of 9 m/s and a mass of 20 kg. What is the kinetic energy of this object

Answer 1

Explanation:

k.e =1/2m(v)²

or

k.e=m/2(v)²

so......k.e=20kg/2(9m/s)²

k.e=10kg(81m²/s²)

k.e=10kg(81m²/s²)

k.e=810kgm²/s²

HOPE ITS CORRECT

ANSWER

k.e=810kgm²/s²

Answer 2

Answer:

810 J
