Vo = 8.50m/s[-23o]
Xo = 8.50*Cos(-23) = 7.82 m/s.
Yo = 8.50*sin(-23) = -3.32 m/s. = Ver.
component of initial velocity.
From the window of a building, a ball is tossed from a height y0 above the ground with an initial velocity of 8.50 m/s and angle of 23.0° below the horizontal. It strikes the ground 6.00 s later. If the base of the building is taken to be the origin of the coordinates, with upward the positive y-direction, what are the initial coordinates of the ball? (Use the following as necessary: y0.)
