Question

A bullet of mass 10 grams is moving with a velocity of 400 + embedded in a freely suspended wooden block of mass 900 grams

Answer 1

Answer:

Mass of bullet(m)= 30g = 0.03kg. ... Distance penetrated by bullet (S) or displacement of bullet in presence of resistive force = 10 cm = 0.1m. ... A gun of mass 5 kg fires a 50 gram bullet with a velocity of 200 m per second.

Answer 2

• We are given that a bullet of mass 10 g moving with a velocity of 400 m/s gets embedded in a freely suspended wooden block of mass 900 g.

• Let the final velocity acquired by the block be 'v m/s'. So, v = 4.4 m/s which means this is the velocity acquired by the block.
