A 0.4kg soccer ball is kicked from a location m (on the ground) with initial velocity m/s. The ball's speed is low enough that air resistance is negligible. Therefore, you can assume that the net force is constant. (Note: the +y direction is defined to be perpendicular to the ground and upward, and the xz plane is the soccer field. t = 0 is defined to be the instant the ball leaves the foot.)
 What is the velocity and position of the ball at t = 0.3 s after being kicked?
 What is the maximum height reached by the ball?
