Hello.
How exactly do I do this???
A ball is thrown vertically upwards at 20 m/s^2. Take g =10m/s, ignore air resistance, take upwards as positive and use the ground as the origin of displacement - the equation of motion is then acceleration = -10. Show that v^2 = 400 - 20x and find the max. height.
