Some European trucks run on energy stored in a rotating flywheel, with an electric motor getting the flywheel up to its top speed of 210 π rad/s. One such flywheel is a solid, uniform cylinder with a mass of 690 kg and a radius of 0.992 m. (a) What is the kinetic energy of the flywheel after charging? (b) If the truck uses an average power of 6.6 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 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? Question 5...
Some European trucks run on energy stored in a rotating flywheel, with an electric motor getting the flywheel up to its top speed of 200π rad/s. One such flywheel is a solid, uniform cylinder with a mass of 350 kg and a radius of 1.1 m. (a) What is the kinetic energy of the flywheel after charging? J (b) If the truck operates with an average power requirement of 9.0 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 180 πrad/s. One such flywheel is a solid, uniform cylinder with a mass of 310 kg and a radius of 1.05 m. (a) What is the kinetic energy of the flywheel after charging? (b) If the truck uses an average power of 9.4 kW, for how many minutes can it operate between chargings?
Trucks can be run on energy stored in a rotating flywheel, with an electric motor getting the flywheel up to its top speed of 627 rad/s. One such flywheel is a solid, uniform cylinder with a mass of 461 kg and a radius of 1.5 m that rotates about its central axis. What is the kinetic energy of the flywheel after charging? (Submit Answer) Tries 0/5 If the truck uses an average power of 8.4 kW, for how many minutes...
please explain ur answer. rotating flywheel. The car a car that makes use of energy stored in a we were to design 8. Suppose is "charged" by using flywheel is a solid homogeneous cylinder with energy of the flywheel after it's been "charged" up? (b) If the car needs to operate with an average power of 8.13 kW, for how many minutes can it operate between chargings? an electric motor to get the flywheel up to its top speed of...
One way to store energy is in the rotational motion of a flywheel, and some have proposed using such technology to power automobiles. One unit is based on a 6.0-kg flywheel in the shape of a hoop of radius 0.11 m that spins as fast as 70000 rpm ▼ Part A How much kinetic energy is stored by the flywheel when it is rotating at its maximum rate? Express your answer to two significant figures and include appropriate units. alue...
