Question: An iron bullet of mass 10 gm moving with speed 100 m/sec towards a stationary iron block of mass 90g...

An iron bullet of mass 10 gm moving with speed 100 m/sec towards a stationary iron block of mass 90gm comes to rest with respect to bigger block after the collision and gets embedded in it. Initial temperature of bullet and block were 500C and 100C respectively. Final temperature of the system of (block + bullet) is (after sufficient long time)

{Given Siron = 400 J/kg-0C, Also assume any energy loss is completely converted into heat}

A

Between 100C and 150C

B

Between 150C and 200C

C

More than 200C

D

None of these

Answer

Between 150C and 200C

Explanation

Solution

Energy lost during collision is distributed among the bodies
