Question

When a bullet is fired from a rifle its momentum become 20 kg m/s. If the velocity of the bullet is 1000m/s what will be its mass?​

Answer 1

Answer:

your answer is here !

Explanation:

Given, Momentum (p) = 20 kg m/s

Velocity (v) = 1000m/s

Mass (m) =?

We know that, Momentum (p) = Mass (m) x Velocity (v)

Therefore, 20 kg m/s = m × 1000m/s

⟹ m=20 /1000

⟹ m= 0.02 kg =20 g

Thus, mass of the bullet = 20 g

follow me !

Answer 2

Answer:

formula of momentum is

p=mv

putting the value

20=m×1000

m=.02
