Problem number 3 (10pts) a particle of mass m is constrained to move on the parabola z=-in the plane, a is a constant length, and there is a constant gravitational force acting in the negative z direction. (a) [3 points] write the lagrangian using as the generalized coordinate of the particle. (b) [2 points] write the equation of motion from the lagrangian? (c) [3 points] write the equation for small oscillations about the equilibrium point. (d) [2 points] what is the angular frequency for the small oscillations in (c)?

An engineer designs a roller coaster so that a car travels horizontally for 152 ft, then climbs 137 ft at an angle of 34.0° above the horizontal. it then moves 137 ft at an angle of 48.0° below the horizontal. if we take the initial horizontal motion of the car to be along the +x-axis, what is the car's displacement? (give the magnitude of your answer, in ft, to at least four significant figures and give the direction of your answer in degrees counterclockwise from the +x-axis.)
