kE of flywheel
kE = 0.5 Iw^2 = 0.5* ( 0.5* m r^2) w^2
kE = 0.25* 461* 1.5^2* 627^2
kE = 1.02* 10^8 J
=========
b)
t = kE / P = 1.02* 10^8 / 8400
t = 202.27

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?

An initially installed flywheel can store 10 J of kinetic energy when rotating at 300 rad/s. It is replaced by another flywheel of the same size but made of a stronger material. If its mass is the same as that of the original, and it is now capable of achieving a rotational speed of 425 rad/s, what maximum energy can be stored? 2.01E+6J O 1.66E+3J O 1.73E+5 J O 1.00E+6J

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...

A car is designed to get its energy from a rotating flywheel with a radius of 1.50 m and a mass of 420 kg. Before a trip, the flywheel is attached to an electric motor, which brings the flywheel's rotational speed up to 4,650 rev/min. (a) Find the kinetic energy stored in the flywheel. 1128x Your response differs from the correct answer by more than 10% Double check your calculations. ] (b) If the flywheel is to supply energy to...

A rotating flywheel has been proposed as a means of temporarily storing mechanical energy in an automobile, providing an energy source for the car. The energy that can be stored in this way is limited by the size and weight of the flywheel and by the maximum angular velocity it can attain without flying apart. Suppose a solid cylindrical flywheel of radius 85.0 cm and mass 90.0 kg rotates at a maximum angular velocity of 270 rad/s. Find the maximum...
