Ok i am not good with physics and these are some review problems for my test coming up. Please help.
At time t1 = 0 an electric grinding wheel has an angular velocity of 28.0 rad/s. It has a
constant angular acceleration of 32.0 rad/s2. At time t2 = 2.20 s a circuit breaker trips, and the
wheel then turns through another 350 rad as it coasts to a stop at constant angular acceleration.
(i) Through what total angle did the wheel turn between t = 0 and the time it again
stopped?
ANSWER: _______________ Rad
(ii) At what time did the wheel stop?
ANSWER: ________________ ____
(iii) What was the angular acceleration of the wheel as it slowed down?
ANSWER: ________________ ____
answers are A1) 489 rad A2) 9.31 sec A3) -13.83 rad/sec^2
Please show work.
