In a ballistics test, a 52g bullet hits a sand bag and stops after moving 1.34 m. If the initial bullat
velocity was 55 m/s what was the magnitude of the average force of friction.

Friction force on the bullet is 58.7 N opposite to its velocity

Explanation:

As we know that initial speed of the bullet is 55 m/s

after travelling into the sand bag by distance d = 1.34 m it comes to rest

so final speed

now we can use kinematics top find the acceleration of the bullet

so we have

now by Newton's II law we know that

so we have

in order to follow the instructions and complete the statements, i need to use data from table c of your student guide. can you think of a way to let me see your student guide for a while ? i can't answer the question without the data in table c.
