Question

A bullet leaves a rifle with a muzzle velocity of 521 m/s. While accelerating through the barrel of the rifle, the bullet moves a distance of 0.854 m. Determine the acceleration of the bullet (assume a uniform acceleration).

Answer 1

Answer:

HEY DEAR HERE IS YOUR ANSWER ✌✌❤❤

The question states that 0.840 m is the distance travelled within the barrel. Therefore u = 0 m/s, v= 521 m/s.  

This means that a = (v² - u²)/2s.  

This is a reformat of v² = u²+ 2as  

a = (521^2)/(2 x 0.840)  

a = 161.57 m/s²

HOPE IT HELPS U.
