Question

Mass of body=2kg, velocity = 3m/s.
What is the order of magnitude of kinetic energy?​

Answer 1

Answer:

9 joule

Explanation :

Mass of body (m)=2 kg

Velocity (v) = 3m/s

Kinetic energy (KE)=?

We have,

KE = 1/2 × m×v^2

= 1/2 × 2 × 3^2

= 9 J

Hence, the order of magnitude of KE is 9 joule.
