Aball, with a mass of 4.5kg, is thrown directly upwards. it reaches a maximum height of 19m from the point at which it was released. using the principle of energy conservation, and ignoring air resistance, calculate the ball's speed when it was released, in m/s. use a gravitational acceleration value of g = 9.8 m/s^2.
