Question

a bullet of mass 30 g is fired from a gun and acquires a velocity of 400 m/s get embedded into a wooden block of mass 470 g Calculate velocity through which wooden block moves​

Answer 1

Answer:

$\huge\underline\orange{\mathcal Answer}$

$\huge\underline{\mathcal Given}$

Bullet :-

Mass = 30 g => 0.03 kg

Velocity = 400 m/s

Wooden Block :-

Mass = 470 g + 0.03 kg (bullet is embedded )

Mass = 0.47 kg + 0.03 kg

$\huge{\boxed{\mathcal Mass=0.5kg}}$

Velocity = v

We know that :-

Momentum of Bullet = recoil momentum of gun

0.03 × 400 = 0.5 × v

12 = 0.5 v

$\huge{\boxed{\mathcal v = 24ms-1}}$
