1.  

A ball is kicked from a location (6,0,-8) (on the ground) with the initial velocity (-9,14,-5) m/s. The ball's speed is low enough that air resistance is negligible. a) What is the velocity of the ball 0.3 seconds after being kicked? (Use the momentum principle) (m/s) b) What is the average velocity of the ball over this time interval? (m/s) c) use the average velocity to find the location of the ball 0.3 seconds after being kicked (m)
