Question

2)At what time does the wheel stop?

3)What was the wheel's angular acceleration as it slowed down?

At time t=0and the time it stopped? 2)At what time does the wheel stop? 3)What was the wheel's angular acceleration as it slowed down? radas it coasts to a stop at constant angular deceleration. 1)Through what total angle did the wheel turn between. From then on, the wheel turns through an angle of 437= 1.60until a circuit breaker trips at time. It has a constant angular acceleration of 27.0a grinding wheel has an angular velocity of 28.0

Explanation / Answer

1.1 =ot +(1/2)t2

=28*1.6+0.5*27*1.62 =79.36 rad

so total angle= 437+79.36 =516.36rad

2.1 =o+t =28+27*1.6 =71.2 rad

(1t/2 )= 437

t=12.3 Seconds

so total =12.3+1.6 =13.9 S
