Question

. A bullet moving with a velocity of 200 ms strikes a wooden block and pierces up to 10 cm into it. Calculate
the magnitude of retardation of the bullet, while piercing the wooden block, assuming the retardation to
be uniform What time is taken by the bullet for piercing through the wooden block
​

Answer 1

Answer: a= -200000 m/s^2

T= 0.001 seconds

Explanation:

Using eqn

v^2 - u^2. = 2as. _-----------(1)

v= u + at. _------------(2).
