Answer:
velocity acquired
by the plank and the bullet equal to 0.15 metre per second
Explanation:
mass of bullet equal to 10 gram
velocity of bullet equal to 1.5 metre per second
total Momentum before collision equal to mass of Plank × velocity
total Momentum for collision equal to total Momentum after collision.
