Question

A futuristic design for a car is to have a large solid disk-shaped flywheel within the car storing kinetic energy. The uniform flywheel has mass 370 kg with a radius of 0.500 m and can rotate up to 230 rev/s. Assuming all of this stored kinetic energy could be transferred to the linear velocity of the 2800-kg car, find the maximum attainable speed of the car.

Step 1

Given: \( m = 370 \, kg \) \( r = 0.500 \, m \) \( \omega = 230 \, rev/s = 230 \times 2\pi \, rad/s \) Substitute the values into the formula: \( I = \frac{1}{2} \times 370 \times (0.500)^2 = 46.25 \, kg \cdot m^2 \) \( KE = \frac{1}{2} \times 46.25 \times (230 Show more…
