A bullet with momentum of 2.8 kg·m/s [E] is traveling at a speed of 187 m/s. The mass of the bullet is: a) 67 g b) 15 g c) 0.067 g d) 0.015 g

Respuesta :

Answer:

The mass of the bullet is 15 g.

(b) is correct option.

Explanation:

Given that,

Momentum = 2.8 kg m/s

Speed = 187 m/s

We need to calculate the mass of the bullet

Using formula of momentum

[tex]P = mv[/tex]

[tex]m = \dfrac{P}{v}[/tex]

Where, P = momentum

v = speed

Put the value into the formula

[tex]m = \dfrac{2.8}{187}[/tex]

[tex]m = 0.015\ kg[/tex]

[tex]m = 15\ g[/tex]

Hence, The mass of the bullet is 15 g.
