The dependence of the angular acceleration of the wheel rotating about a fixed axis perpendicular to its plane and passing through its center, the time given by the equation e = 3t 2 + 2 ^ (p ^ -2). The radius of the wheel 0.3m, 20kg weight is evenly distributed on the rim. Define: angular path traversed during the time from t1 = t2 = 1s 3s; total number of revolutions made by the wheel during this time; linear speed of points on the wheel rim; momentum of the wheel at time t = 3c (at t = 0, w = 0).
Detailed solution shorthand terms, formulas and laws used in the decision, the withdrawal of the calculation formula and the response.
If you have any questions to address, please. I´ll try to help.
