Answer #1
GivenThe initial velocity of the bullet vo= 0Themuzzle of a rifle with a speed v =600m/sDistance x= 0.90 m---------------------------------------------------------------------From the kinematic relations,v2 =vo2+ 2axThe acceleration of the bullet while in the barrel isa = [v2-vo2]/(2x)= [(600 m/s)2 -0]/(2(0.90m))=2.0x105m/s2
