tennis ball machine fires a ball vertically upwards at time
t = 0 at 19.6 m/s. Assume that air resistance is negligible and
take g = 9.8 m/s2
.
a) Calculate the displacement and velocity of the ball at
t = 1.0 s, 2.0 s, 3.0 s and 4.0 s.
b) Use your answers to part a) to draw
i) a graph of displacement against time for the ball
ii) a graph of velocity against time for the ball.

v(t) = 19.6 - 9.8t
so, that's a straight line.

And of course, displacement is just a parabola
s(t) = 19.6t - 4.9t^2
