    A 30 g Arrow is shot through a 8 cm thick apple. If the arrow enters the apple at 30 m/s and exits in the same direction at 25 m/s, with what force has the apple resisted the arrow?

    I know that the apple slowed the arrow down 5 m/s. I also know F=MA but how do I figure out the acceleration? Or am I going about this question completely wrong? Is there a way to find force directly?

    Thanks

    i won't do it for you

    all im going to tell you is that you use this formula to work out acceleration: v2 = u2 + 2aS
