The flywheel in a car is a solid cylinder with a mass of 95 kg,
a radius of 10 cm, and a length of 5.0 cm. It is rotating about an
axis through its center (Table 11.2 (c)) at 5000 rpm (revolutions
per minute).
(a) What is the kinetic energy of the cylinder?
J
(b) Suppose that all this rotational kinetic energy could be
transformed into translational kinetic energy of the car, mass 1200
kg. If the car started from rest, what would its final speed
be?
m/s

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...
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...
Please also help with the last part /20 points A bus contains a 1,500 kg flywheel (a disk that has a 0.600 m radius) and has a total mass of 10,000 kg. (a) Calculate the angular velocity (in,rad/s) the flywheel must have to contan 10.4 P 027. angular velocity (in, rad/s) the flywheel must have to contan enough energy to take the bus from rest to a speed of 26.0 m/s, assuming 88.0% of the rotational energy , kinetic energy...
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 flywheel is a solid disk that rotates about an axis that is perpendicular to the disk at its center. Rotating flywheels provide a means for storing energy in the form of rotational kinetic energy and are being considered as a possible alternative to batteries in electric cars. The gasoline burned in a 159-mile trip in a typical midsize car produces about 1.53 x 109 J of energy. How fast would a 14.3-kg flywheel with a radius of 0.203 m...
A flywheel is a solid disk that rotates about an axis that is perpendicular to the disk at its center. Rotating flywheels provide a means for storing energy in the form of rotational kinetic energy and are being considered as a possible alternative to batteries in electric cars. The gasoline burned in a 220-mile trip in a typical midsize car produces about 4.20 x 109 J of energy. How fast would a 48.9-kg flywheel with a radius of 0.255 m...
