Question

From the window of a building, a ball is tossed from a height y0 above the ground with an initial velocity of 8.80 m/s and angle of 16.0° below the horizontal. It strikes the ground 4.00 s later. 

With the positive x-direction chosen to be out the window, find the x- and y-components of the initial velocity.

vix =  m/s
viy =  m/s

How far horizontally from the base of the building does the ball strike the ground?
 m
