Answer:
The speed of the two stuck together blobs of putty immediately after colliding = 1.5 m/s
Explanation:
The momentum is conserved before and after collision. That is initial momentum value is equal to final momentum value.
Initial momentum = 2 * 3+ 2 * 0 = 6 kg m/s
So final momentum = 6 kg m/s
Final mass of body = 2 + 2 = 4 kilogram
Final velocity of body = Final momentum/ Final mass = 6/4 = 1.5 m/s
So, the speed of the two stuck together blobs of putty immediately after colliding = 1.5 m/s
