An arrow is accelerated for a displacement of 75cm [fwd] while it is on the bow. If the arrow leaves the bow at a velocity of 75m/s [fwd], what is the average acceleration while on the bow?

  • physics 3U - ,

    a = change in speed / time

    average speed = (75/2 )meters/ second
    so time = distance/speed = .75meters/(75/2 meters/second) =2*10^-4 seconds
    acceleration = 75/2*10^-4 = 372500 m/s^2
