Question

a bullet of 5 gram is fired from a pistol of 1.5 kg if the recoil velocity of pistol is 1.5 m per second find the velocity of bullet

Answer 1

As per the question, the mass weight of the bullet is 5gm.5gm = 5/1000 kg = 0.005 kg/The pistol weighs 1.5 kg.

The velocity of the pistol is 1.5 m /second

We have to find out the velocity of the bullet..Suppose, it is V.

So, the velocity of the bullet (V) = mass of pistolx velocity of pistol / mass of bullet.or, V= 1.5 x 1.5 / 0.005.or, V = 2.25 / 0.005.or, V = 450 m / second.

The velocity of the bullet is 450 m/sec.

Answer 2

Answer:

Explanation:here we use v=1 .5×1.5\0.005
