Question
Calculate the kinetic energy of a body of mass 2 kg moving with a velocity of 0.1 meters per second.
- 0.01 J
- 0.02 J
- 0.04 J
- None of these
Hint:
Kinetic energy can be calculated by 1/2 mv2
The correct answer is: 0.01 J
Given:
Mass of the body = 2kg
The velocity of the body = 0.1 ms-1
To find:
Kinetic energy=?
Solution:
Answer:
The kinetic energy of the body is 0.01J
