Aball is kicked from a location < 8, 0, -7> (on the ground) with initial velocity < -8, 19, -3> 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 ) what is the average velocity of the ball over this time interval? (c) use the average velocity to find the location of the ball 0.5 seconds after being kicked.
