What is the kinetic energy of an object that has a mass of 50.0kg and a velocity of 18 m/s?

Answer

The kinetic energy is 8100 J.

Explanation

Mass is 50.0kg and velocity is 18 m/s, the kinetic energy is:

As we know the formula of kinetic energy which is K. E = ½ (mv ^ 2),

mass = m = 50.0kg

velocity = v = 18 m / s,

by putting values in the formula,

K. E = ½ (mv ^ 2),

K. E = ½ (50kg). (18 m / s) ^ 2

K. E = ½ (50kg). (324),

=> K. E = 1/2 (16200),

=> K. E = 16200 / 2,

=> K. E = 8100J.

Hence, the kinetic energy (K. E) is 8100 joule (J).
