The flywheel of an engine is rotating at 35.0 rad/s. When the engine is turned off, the flywheel slows at a constant rate and stops in 19.0 s. Calculate (a) the angular acceleration of the flywheel, (b) the angle through which the flywheel rotates in stopping, and (c) the number of revolutions made by the flywheel in stopping.

a.

b.

c.52.9 rev

Explanation:

We are given that

Initial angular speed of wheel=

Time=t=19 s

Final angular speed=

a.We have to find the angular acceleration of the wheel.

We know that

Angular acceleration

Using the formula

b.

Using the formula

c. rad=1 rev

1 rad= rev

332.5 rad=

Number of revolutions made by the flywheel in stopping=52.9 rev

b

step-by-step explanation: a third of 24 is 8, 8 times 3 is 24 so 8 - 2 would be 6

jupiter is the largest planet in our solar system, having a mass and radius that are respectively, 318 and 11.2 times that of earth. suppose that an object falls from rest near the surface of each planet and that the acceleration due to gravity remains constant during the fall. each object falls the same distance before striking the ground. determine the ratio of the time of fall on jupiter to that on earth.
