Question

If the velocity of a body of constant mass m changes from v0 to v, the impulse developed by the body is given by:
Options
A m(v + v0)
B m(v - v0)
Correct Answer
C ½ m(v² - v0²)
D m a
Correct Answer

Option B is the correct answer.

Detailed Explanation

Impulse is defined as the change in linear momentum. For a constant mass, the change in momentum is m(v - v0). Option D (ma) is force, and option C is related to kinetic energy.

Hint

Impulse equals the change in momentum.
