Atorque of 50 n*m acts on a wheel of moment of inertia 25 kg*m^2 for 4 s and then is removed.
b)how many revolutions does it make in 15 s if it starts at rest?
i found the angular acceleration, 2 rad/s^2, but i don't know how to find the amount of revolutions.

Lin yao looks at the back of a spoon. how should she describe her reflection? upside down and smaller upside down and larger right-side up and smaller right-side up and larger

Science and technology are interdependent. advances in one lead to advances in the other. give an example of this phenomenon.

Suppose a wheel with a tire mounted on it is rotating at the constant rate of 2.15 times a second. a tack is stuck in the tire at a distance of 0.373 m from the rotation axis. noting that for every rotation the tack travels one circumference (a) find the tack's tangential speed. (b) what is the tacks radial acceleration?
