3. For Grading Knight 12.64 Flywheels are large, massive wheels used to store energy. They can be spun up slowly, then the wheel's energy can be released quickly to accomplish a task that demands high power. An industrial flywheel has a 1.5 m diameter and a mass of 250 kg. Its maximum angular velocity is 1200 rpm. a. A motor spins up the flywheel with a constant torque of 50 Nm. How long does it take the flywheel to reach...

Trucks can run on energy stored in a rotating flywheel with an electric motor getting the flywheel up to its top speed of 847 radians per second. The flywheel is a solid, uniform cylinder with a mass of 461 kg and a radius of 0.939 meters. If the trucks uses an average power of 8.0 kW, for how many minutes can it operate before the flywheel needs to be "charged" again? By "charging" we mean the electric motor adds energy...
Some European trucks run on energy stored in a rotating
flywheel, with an electric motor getting the flywheel up to its top
speed of 160 π rad/s. One such flywheel is a solid, uniform
cylinder with a mass of 270 kg and a radius of 1.07 m. (a) What is
the kinetic energy of the flywheel after charging? (b) If the truck
uses an average power of 6.2 kW, for how many minutes can it
operate
between chargings?

Some European trucks run on energy stored in a rotating flywheel, with an electric motor getting the flywheel up to its top speed of 320 π rad/s. One such flywheel is a solid, uniform cylinder with a mass of 690 kg and a radius of 0.784 m. (a) What is the kinetic energy of the flywheel after charging? (b) If the truck uses an average power of 7.7 kW, for how many minutes can it operate between chargings?
A high-speed flywheel in a motor is spinning at 500 rpm when a power failure suddenly occurs. The flywheel has mass 43.0 kg and diameter 72.0 cm . The power is off for 34.0 s and during this time the flywheel slows due to friction in its axle bearings. During the time the power is off, the flywheel makes 150 complete revolutions. At what rate is the flywheel spinning when the power comes back on? How long after the beginning...
