The position of a softball tossed vertically upward is described by the equation y = 7.00t - 4.90 t2, where y is in meters and t in seconds.
A) Find the balls initial speed in (m/s) v0 at t = 0?
B) Determine the velocity component vy (in m/s) of the ball at t = 1.26 s?
C) Determine the component ay of the acceleration (in m/s2) of the ball at t = 1.26 s?
