I need some help with this classical mechanics question. (b)•CooooooooTo1. Consider the mass M at the end of a massless spring whosespring constant is k and whose relaxed length is l. The pendu-lum/spring is fixed at the opposite (to the mass) end, but can.freely rotate in the plane of the paper about that fixed point asshown. THERE IS NO GRAVITY FOR THIS PROB-LEMIn terms of , M and the generalized coordinates r and 0, write the Lagrangian.What are the equations of motion for r and 0?List conserved quantities, expressing them in terms of r, r, 0, 0, and the pa-rameters k, l, M.

There's an issue with this answer. My result can not be greater than one since it wants it in terms of the speed of light. For instance, 0.78c is 78% the speed of light.
In 1977 the planet Alderaan, with a mass of 3 x 1024 kg, exploded. Assuming it was initially at rest and experienced no external interactions, 3. A) If the planet blew apart into two pieces with 40% of its mass flying away in one piece at 4,000 km/s, what speed did the rest of the planet have relative to its original frame? B) If the planet blew apart into three pieces, with 30% of its mass flying away at 3,000 km/s, and 20% of its mass flying away at 5,000 km/s at an angle of 120° relative to the velocity direction of the first fragment, what velocity did the rest of the planet have? Report the direction by specifying its angle relative to the velocity direction of the first fragment.
Show that a potential difference of 1.02 x 106 V would be sufficient to give an electron a speed equal to twice the speed of light if Newtonian mechanics remained valid at high speeds. (b) What speed would an electron actually acquire in falling through a potential difference equal to 1.02 x 106 V ?
