# Energy From Endpoints

A rigid rod in the $$xy$$-plane is $$2\text{ m}$$ long and has a mass of $$1\text{ kg}$$. The rod is free to move.

The instantaneous velocity of one of its ends is $$(v_{x_1},v_{y_1}) = (0,3)\text{ m/s},$$ and the instantaneous velocity of the other end is $$(v_{x_2},v_{y_2}) = (2,1)\text{ m/s}.$$

What is the kinetic energy of the rod (in Joules, to 3 decimal places)?
