Abullet with a mass of 3.0 gram, moving at speed of 300 m/s, hits and embeds itself in the trunk of a tree. the tree exerts an average force of 250 n on the bullet. what is the distance the bullet travels inside the trunk?

Explanation:

We have equation for force

          Force = Mass x Acceleration

          Force = 250 N

         Mass = 3 g = 3 x 10⁻³ kg  

         250 = 3 x 10⁻³ x Acceleration

         Acceleration = 83333.33 m/s²

Deceleration of bullet is 83333.33 m/s².

We have equation of motion v² = u² + 2as

Initial velocity, u = 300 m/s  

Acceleration, a = -83333.33 m/s²  

Final velocity, v = 0 m/s  

Substituting  

v² = u² + 2as

0² = 300² + 2 x -83333.33 x s

s = 0.54 m  

Distance the bullet travels inside the trunk is 0.54 m  

explanation:

a fuel engine ( known as a gasoline engine in american english )is an internal combustion engine with spark ignition, designed to run on petrol (gasoline) and similar volatile fuels.
