A bullet of mass 20g moving with a velocity of 100m/s strikes a wooden block of mass 80g and gets embedded into it . Calculate the velocity of the combined system .

Open in App

Solution

The answer can easily be calculated using Momentum Conservation.

Initial Momentum = Final Momentum

20100=(80+20)V

where v is the final velocity of (bullet + block) system.

v= 2000/100*

v = 20 m/sec
