SATHEE: Kinematics Question 334

Kinematics Question 334

Question: A bullet fired into a wooden block loses half of it’s velocity after penetrating 40 cm. It comes to rest after penetrating a further distance of

Options:

A) $\frac{22}{3} c m$

B) $\frac{40}{3} c m$

C) $\frac{20}{3} c m$

D) $\frac{22}{5} c m$

Show Answer

Answer:

Correct Answer: B

Solution:

For first part of penetration, by equation of motion $(\frac{u}{2}) - {(u)}^{2} = 2 a S or a = - \frac{3 u^{2}}{8 S} \dots . (i)$ For latter part of penetration ${(0)}^{2} - {(\frac{u}{2})}^{2} = 2 a S or a=- \frac{3 u^{2}}{8 S} \dots . (i)$

$S^{'} = \frac{S}{3} {or S}^{'} = \frac{40}{3} c m$
