Question

Calculate the kinetic energy when: Mass = 15 kg Velocity = 20 m/s

Answer 1

3000 J

Step-by-step explanation:

Given,

Mass ( m ) = 15 kg

Velocity ( v ) = 20 m/s

To find : Kinetic Energy ( K.E )

Formula

K.E = mv²/2

K.E = 15 × 20²/2

= 15 × 20 × 20/2

= 15 × 20 × 10

K.E = 3000 J

Note

J is Joule.

Joule is the unit of Kinetic Energy.
