If a bullet of mass $5 g$ moving with velocity $100 m s^{- 1}$ , penetrates the wooden block up to $6 cm$ . Then the average force imposed by the bullet on the block is

Options:

Answer:

Solution:

$u = 100 m s^{- 1}, v = 0, s = 0.06 m$

Retardation $= a = \frac{u^{2}}{2 s} = \frac{{(100)}^{2}}{2 \times 0.06} = \frac{1 \times 1 0^{6}}{12}$

$∴$ Force $= m a = \frac{5 \times 1 0^{- 3} \times 1 \times 1 0^{6}}{12} = \frac{5000}{12} = 417 N$
