Question

Calculate the kinetic energy of a 150kg. object that is moving with a speed of 15 m/s?

Answer 1

kinetic energy=$\frac{1}{2}mv^{2}$

here m=150kg

        v=15m/s

therefore energy=0.5*150*15*15 J

                energy=16875 J

Answer 2

Given:

The Mass of the object = 150 Kg.

The Speed of the object = 15m/s.

To Find:

The kinetic energy of the object.

Solution:

The formula used for calculating the kinetic energy is,

K.E = ½MV²

Where,

K.E is the kinetic energy of the object.

M is the mass of the object.

V is the velocity of the object.

Now, putting the values we have in the equation, we get,

K.E = ½ x 150 x (15)²

= 16,875 joules

Hence, the Kinetic energy of the object is 16,875 joules.
