2. What's the kinetic energy of an object that has a mass of 12 kilograms and moves with a velocity of 10 m/s?

Let us solve for it

Explanation:

Energy

It is ability to do work.

There are so many forms of energy.

out of which mechanical energy is also one of the form.

Mechanical energy

It is the energy possessed by the body by virtue of its motion and state.

It is of two types:

Kinetic energy Potential energy

Kinetic energy

It is the energy possessed by the body by virtue of its motion.

Its expression is:

K. E=1/2mv²

Here in above question it is given that:

mass = 2Kg

V=10m/sec

K. E will be = 1/2 x 2 x 10 x 10

K. E=100 J
