Answer 2

Given:

• Mass (m) = 2 kg
• Velocity (v) = 0.1 m/s

To Find:

• What is the Kinetic energy?

Formula Used:

Kinetic energy = ½ × Mass × (velocity)²

E.k. = ½ × Mv²

Solution:

According to the Formula,

After putting the values;

➣ E.k = ½ × 2 × (0.1)²

➣ E.k = ½ × 2 × 0.1 × 0.1

➣ E.k = 0.01 j

Hence,

The Kinetic energy of the body is 0.01 Joules.

Remarks:

• E.k = Kinetic energy
• M = Mass
• SI unit of Energy is joules (j).
