A particle of mass m is projected with velocity v making an angle of 45^ with the horizontal. When the particle lands on the level ground the magnitude of the change in its momentum will be

Options

  1. A2 m v
  2. Bm v / 2
  3. Cm v 2
  4. Dzero

Correct answer

C. m v 2

Step-by-step solution

The horizontal momentum does not change. The change in vertical momentum is aligned m v -(-m v ) &=2 m v 1 2 &= 2 mv aligned
