At time t=0 a grinding wheel has an angular velocity of 26.0 rad/s . it has a constant angular acceleration of 30.0 rad/s2 until a circuit breaker trips at time t = 2.20 s . from then on, the wheel turns through an angle of 440 rad as it coasts to a stop at constant angular deceleration. through what total angle did the wheel turn between t=0 and the time it stopped? express your answer in radians. at what time does the wheel stop? express your answer in seconds. what was the wheel's angular acceleration as it slowed down? express your answer in radians per second per second.

Modify the equation fδt=δ (mv) to find the force of friction.

If the wheels lock when braking suddenly the vehicle: a: loses traction b: lose steering wheel ability c: gain speed slightly d: gain steering ability
