    How Does Wood Resistance Affect Bullet Penetration and Stoppage Time?

    Yes it is m/s^2 I mistakenly typed N. I tried to brake the problem up into 2 parts. Part 1: Time of bullet in barrel, with 0 acceleration so d = v * t .56m = 350 m / s * t t = .56 m * s / 350 m = .0016 seconds Part 2: Time it enters the wood until the bullet stops. vf =vi + a...

    How Does Wood Resistance Affect Bullet Penetration and Stoppage Time?

    Homework Statement A rifle with a barrel length of 56 cm fires a 10 g bullet with a horizontal speed of 350 m/s. The bullet strikes a block of wood locked in position and penetrates to a depth of 13 cm. What resistive force (assumed to be constant) does the wood exert on the bullet...

    What Forces Act on a Car Pushing a Block in Physics?

    is "force by rabbit" the same as force of car on rabbit? I interpreted that as the equal and opposite reaction push back onto the car from the rabbit.
