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

Aplayground merry-go-round has a radius of 4.6 m and a moment of inertia of 200 kg-m2 and turns with negligible friction about a vertical axle through its center. a child applies a 26.0 n force tangentially to the edge of the merry-go-round for 15.0 seconds. if the merry-go-round is initially at rest, how much work did the child do on the merry-go-round?
