Linear Momentum of a Falling Chain

CLMECH-1NWMLZ

A uniform chain with a mass of 1.8 kg and a length of 1.2 m hangs over a table. The top end of the chain is attached to the ceiling by a thin thread. The bottom end of the chain is just touching the table. The thread breaks suddenly and the chain falls onto the table.

Find the total linear momentum that the chain transfers to the table.

A

8.7 kg $\cdot$ m/s

B

6.2 kg $\cdot$m/s

C

5.8 kg $\cdot$m/s

D

4.1 kg $\cdot$m/s
