Acceleration of the bullet is -87500m/s2
The rate at which the velocity of an object varies in relation to time is known as acceleration.
Acceleration is a vector quantity and the direction of the net force applied on an item determines the direction of its acceleration.
Acceleration is the rate at which the speed and direction of a moving object vary over time. When anything moves faster or slower moving straight, it is considered to be accelerating. Even though the speed is constant, motion on a circle accelerates because the direction is always shifting. Both effects influence to the acceleration for all other motions.
Since acceleration has both a magnitude and a direction, it is considered as a vector quantity. The velocity vector change during a time interval divided by the time interval is the definition of acceleration.
The limit of the ratio of the variation in velocity during a specified time period to the time period as the time period approaches zero determines the instantaneous acceleration (at a specific time and location).
Formula:
[tex]v^2 = u^2 + 2aS[/tex]
[tex]a = (v^2 - u^2) / 2S[/tex]
[tex]a = -350^2 / 2 * 0.07[/tex]
[tex]a = -122500 / 0.14[/tex]
[tex]a = -87500 m/s^2[/tex]
