Question

3. From a rifle of mass 4 kg, a bullet
of mass 50 g is fired with an
initial velocity of 35 m s.
Calculate the initial recoil velocity
of the rifle.​

Answer 1

$\mathfrak{\huge{\green{\underline{\underline{Answer :}}}}}$

M = 4 kg              m  = 50 gms

v  = 35 m/sec

Initial momentum of rifle and bullet together = 0.  So  as per the conservation of linear momentum,

       0 = M * (-V) +  m  v 

=>     0   = 4 * (-V) + 50/1000  * 35

 

V =  0.4375 m/sec  (recoil velocity)
