Do this with the roller costar in class and the 25 mm (0.067 kg) ball in projectile launcher with spring constant (k) of 200 N/m A ball of 0.067 kg is pushed against a spring of spring constant k = 200. N/m compressing the spring 0.055 m. What will be the speed of the ball as it is projected out of the launcher?
