A bullet traveling at 350 m/s hits a tree, penetrating 0.125 m into the tree before stopping. The mass of the bullet is 0.200 kg. Treat the force the tree exerts on the bullet to stop it as a constant force. a) How big is the acceleration the bullet experiences when it hits the tree

Explanation:

The motion of the bullet is a uniformly accelerated motion, therefore we can find its acceleration by using the following suvat equation:

where

v is the final velocity

u is the initial velocity

a is the acceleration

s is the distance covered

For the bullet in this problem:

u = 350 m/s is the initial velocity of the bullet

v = 0 is the final velocity (the bullet comes to a stop)

s = 0.125 m is the stopping distance of the bullet

Therefore, by solving the equation for a, we find its acceleration:

And the negative sign tells that the direction of the acceleration is opposite to that of the velocity.

where's the following? you gotta add it to know what the choices are

explanation:

think its the third option
