An experimental car is designed to work by accumulating energy in a flywheell shaped as a uniform solid disc. To make the car move, the flywheel is "charged" by attaching it to an external machine able to exert a torque on the wheel of t = flywheel is accelerated and accumulates rotational kinetic energy. The friction of the flywheel with its axle bearings is negligible, and it has a radius R = 1.3 m and a mass m = 631.5 kg. 1000 Nm, so that the %3D %3D a) Find the moment of inertia of the flywheel. (you can assume it is a uniform disk.)

Special Relativity

The theory of special relativity discusses how space and time are related to objects traveling along a straight line at a constant speed. Simply stated, as an object reaches the speed of light, its mass becomes infinite and it is unable to move faster than light. This interstellar speed limit has been the topic of much debate in astronomy, and also in science fiction when people consider how to fly over large distances.
