A spring is used to launch a marble at a 30o angle. The spring has a constant of 55N/m. The marble has a mass of 0.01kg. Before launch, the spring is compressed by 0.05m. a. Calculate the launch speed of the marble (note: you may assume the spring simply hits the marble, so there is no change in height during the actual launch). (3 points) b. The barrel of the launcher is 1.25m above the floor. Calculate how far the marble lands from the base of the launcher. (6 points)
