We have that the  initial velocity   is mathematically given as

V1=86.4m/s

<h3>Velocity</h3>

Question Parameters:

  • A 0.05 kg arrow
  • Is fired at a velocity towards a 1.2 kg apple.
  • The arrow sticks in the apple and both move at 3.6m/s.

Generally the equation for the Conservation of momentum   is mathematically given as

M1V1=M2V2

Therefore

0.05*V1=1.2*3.6

V1=(1.2*3.6)/0.05

V1=86.4m/s
