A baseball pitcher throws a baseball with a speed of 38 . In throwing the baseball, the pitcher accelerates the ball through a displacement of about 3.5 , from behind the body to the point where it is released Estimate the average acceleration of the ball during the throwing motion

  • college -

    the ball starts with a speed of 0 and accelerates to 44 m/s in a distance of 3.5m

    use:

    vf^2=v0^2+2ad

    vf=final speed = 44m/s
    v0=initial speed = 0
    a=accel (to be determined)
    d= distance = 3.5 m

    44^2=0+2ax3.5

    a=44^2/7 = 276.6 m/s/s
