Question

A futuristic design for a car is to have a large flywheel within the car to store kinetic energy. The flywheel is a solid uniform disk of mass 370 kg with a radius of 0.50 m, and it can rotate up to 200 rev/s. Assuming all of this stored kinetic energy could be transferred to the linear speed of the 1500-kg car, find the maximum attainable speed of the car.

Step 1

Given: - Mass of flywheel, \( m = 370 \, kg \) - Radius of flywheel, \( r = 0.50 \, m \) - Angular velocity, \( \omega = 400 \pi \, rad/s \) Calculate: \( I = \frac{1}{2} \times 370 \times (0.50)^2 = 46.25 \, kg \cdot m^2 \) \( KE = \frac{1}{2} \times 46.25 Show more…
