a ball of mass 0.5 kg is shot upwards from the floor with an inital speed of 2.0m/s. assume that there is no air resistance (take g= 10 m/s^2) A) by using the conservation of energy, calculate the maximum height reached by the ball B)by using the conservation of energy, calculate the speed of the ball when it reaches a height of 0.1 m
