In the barrel of the gun, the ball is accelerated from rest to vbest (3.28m/s). From the one click position on the launcher, the ball travels approximately 1 cm before leaving the barrel. Given your value for vbest, what is the average acceleration felt by the ball as it is being launched in the barrel?  Is this magnitude of acceleration reasonable
