A flywheel with a very low friction bearing takes 1.6 h to stopafter the motor power
Nina [5.8K]

Answer:

(I). The initial rotation rate is 4.29 rad/s.

(II). The revolutions is 3932.

Explanation:

Given that,

Time = 1.6 h

Angular velocity = 41 rpm

(I). We need to calculate the initial rotation rate in rad/s

\omega=41\ rev/m

\omega=\dfrac{41\times 2\pi}{60}\ rad/s

\omega=4.29\ rad/s

(II). We need to calculate the revolutions

Using formula of revolutions

\theta=\omega t

\theta=4.29\times1.6\times3600

\theta=24710\ rad

\theta=\dfrac{24710}{2\pi}

\theta=3932\ revolution

Hence, (I). The initial rotation rate is 4.293 rad/s.

(II). The revolutions is 3932.

Rocket-powered sleds are been used to test the responses of humans to acceleration. Starting from rest, one sled can reach a spe
erik [133]
Hi, I crunched some numbers for you and got the following results:

Starting from initial velocity of zero (rest) the sled reached a top speed of 257.3 m/s^2.
Upon slowing down or braking, the sled slowed down very hard to about 76.35 m/s^2.
Acceleration and Gravitational Acceleration were the main interpretations obviously in this problem. 
Also, if my math was correct, the speed of the sled slowing down was around 7.7 G's (acceleration due to gravity)! That is about on par with the acceleration of a F-16 Fighter Jet pulling out of a dive!--> (79 m/s^2) The human test subject probably came close to blacking out I would guess as well or very close to!
