Question

A bullet of mass 50 g if fired from a gun it give with velocity of 100 m/s in 0.01 seconds calculate the power expand by the tone from firing the bullet​

Answer 1

Answer:

we know that

MV=-mu

v=-mu/M

M= the gun's mass.

m=the bullet's mass.

u=the velocity of the bullet.

V=the velocity of the gun's backward motion.

here u=o

m=50g.

M=100m/s

v=???? is our question.

V=-mu/M

= 50×0/100

=50/100

=0.5gcm/s
