Question
A bullet of mass 0.25 kg is fired with velocity 302 m/s into a block of wood of mass m1=37.5kg.It gets embedded into it.The block m1 is resting on a long block m2 and the horizontal surface on which it is placed is smooth.The coefficient of friction betweeen m1 and m2 is 0.5.Find the displacement of m1 on m2 and the common velocity of m1 and m2.Mass m2=1.25kg.
