Question
A bullet of mass m strikes a block of mass M connected to a light spring of stiffness k, with a speed V0. If the bullet gets embedded in the block then, the maximum compression in the spring is :
Options
A.
B.
C.
D.
Solution
Velocity of the system just after the collision
mvo = (m + M) V′ ⇒ V′ =
0 −
(m + M) V2 = 0 + 0 − 
K X2max
= K X2max ⇒ Xmax = 
mvo = (m + M) V′ ⇒ V′ =
0 −
(m + M) V2 = 0 + 0 − K X2max = K X2max ⇒ Xmax = Create a free account to view solution
