A simple model for a pouncing cat is a mass that follows a curved trajectory after being launched from a spring. Imagine a 0.057 kg mass launched by a spring. The spring has a spring constant 3,775 N/m. The mass is launched at an angle of 9 degrees above horizontal. The spring is initially compressed a distance of 24.5 mm. At the peak of its trajectory, the speed of the mass is 1.4 m/s. What is the increase in height (in units of m) of the mass at the peak of its trajectory
