Question

A bullet comes out of a 2.0 m length gun tube at a velocity of 80 m / s. Find the average acceleration of the bullet.​

Answer 1

Answer

1600ms-2

Explanation

final speed of bullet 80ms-1

initial speed of bullet= 0 ms-1(because the bullet was at rest before pulling off the trigger)

distance traveled by the bullet is 2 m (considering gun to be a hollow pipe)

therefore

by third equation of motion we get

v^2-u^2=2as

(80)^2-0=2*2*a

6400/2=a

a=1600m/s^2

correct if wrong

mark as brainliest if right

best of luck
