Question

What is the kinetic energy of a 0.150 kg
object moving at a velocity of 100m/s?

Answer 1

750J

Step-by-step explanation:

Given parameters:

Mass of the object = 0.15kg

Velocity of the object = 100m/s

Unknown:

Kinetic energy of the body = ?

Solution:

The kinetic energy is the energy due to the motion of a body. It is mathematically expressed as;

K.E =
`(1)/(2)` m v²

m is the mass of the body

v is the velocity

Now insert the parameters and solve;

K.E =
`(1)/(2)` x 0.15 x 100² = 750J
