A 50 g bullet moving with velocity 10 m/s strikes a block of mass 950 g at rest and gets embedded in it. The loss in kinetic energy will be
Text Solution
Verified by ExpertsThe correct answer is:
B
Initial K.E. of system = K.E. of the bullet = 
By the law of conservation of linear momentum
⇒ ⇒ 
Fractional loss in K.E. = 
By substituting 
we get
Fractional loss = 
∴ ∴ Percentage loss = 95%
