At t=0 a grinding wheel has an angular velocity of 25.0 rad/s. It has a constant angular acceleration of 26.0 rad/s2 until a circuit breaker trips at time t = 2.40 s. From then on, it turns through an angle 435 rad as it coasts to a stop at constant angular acceleration.
Part APart complete Through what total angle did the wheel turn between t=0 and the time it stopped? Express your answer in radians. θ = 570 rad
Part B At what time did it stop? Express your answer in seconds. t = nothing s
Part C What was its acceleration as it slowed down? Express your answer in radians per second squared.
a) The total angle of the grinding wheel is 569.88 radians,
b) The grinding wheel stop at t = 12.354 seconds,
c) The deceleration experimented by the grinding wheel was 8.780 radians per square second.
