In the classic game of Pinball, a ball is launched by a spring. The spring is compressed by 6.308mm, the ball weighs 140.143g, and is found to be travelling at 0.4076m/s. Assuming no friction or air resistance, and assuming all of the energy in the spring is transferred to the ball, what is the spring constant of the spring? Use Sl units
