A spring with spring constant k = 400 N/m is used to launch a mass m = 2.0 kg up a frictionless inclined plane having an angle of elevation θ= 37o. What is the maximum vertical height reached above the starting elevation (the ground) of the mass during the motion of the mass if the spring is compressed a distance d = 0.2m before the launch? Assume no friction during the motion and use g = 10 m/s2.
