If a body loses half of its velocity on penetrating 3 cm in a wooden block, then how much will it penetrate more before coming to rest
Text Solution
Verified by ExpertsThe correct answer is:
A
For first condition
Initial velocity = u, Final velocity = u/2, s = 3 cm
From 
⇒ ⇒ 
⇒ ⇒ 
Second condition
Initial velocity = u/2, Final velocity = 0
From 
⇒ ⇒ 
∴ ∴
