A football is thrown horizontally with an initial velocity of (14.8 m/s)x. Ignoring air resistance, the average acceleration of the football over any period of time is (-9.81 m/s2)y. Calculate the velocity vector of the ball 1.56 s after it is thrown. Give the answer in term of the x- and y-components. Enter the x-component first.

Calculate the magnitude of the velocity at this time.

Calculate the direction of the velocity with respect to the positive x-axis at this time. Use positive as up and negative as down.
