When s=0, the spring on the firing mechanism is unstretched. If the arm is pulled back such that s=0.1m and released, determine the speed of the 0.3kg ball when the angle θ =60 deg. Also find the normal reaction between the circular track and the ball at the same angle θ =60 deg. Also, at what angle will the ball leave the track?
