A machinist turns on the power to a grinding wheel, which is at rest at t = 0.0 s. The wheel accelerates uniformly for 8.0 s and reaches the operating angular velocity of 80 rad/s. The wheel is then run at that angular velocity for 30 seconds and then the power is shut off. The wheel decelerates uniformly at 5.0 rad/s2 until the wheel stops. Through what total angle has the wheel turned?
(a) 2400 radians (b) 3360 radians (c) 4800 radians (d) 3520 radians (e) 4120 radians
The correct answer is B. Please explain how you arrived at your answer.

A machinist turns the power on to a grinding wheel, which is at rest at time t = 0.00 s. The wheel accelerates uniformly for 10 s and reaches the operating angular velocity of 86 rad/s. The wheel is run at that angular velocity for 32 s and then power is shut off. The wheel decelerates uniformly at 2.3 rad/s2 until the wheel stops. In this situation, the time interval of angular deceleration (slowing down) is closest to: 37 s...
A machinist turns on the power on to a grinding wheel at time t = 0s. The wheel accelerates uniformly from rest for 10s and reaches the operating angular speed of 58 rad/s. The wheel is run at that angular velocity for 30s, and then power is shut off. The wheel slows down uniformly at 1.4 rad/s^2 until the wheel stops. What is the total number of revolutions made by the wheel in this situation ? A machinist turns on...
A machinist turns the power on to a grinding wheel, at rest, at time t = 0 s. The wheel accelerates uniformly for 10 s and reaches the operating angular velocity of 40 rad/s. The wheel is run at that angular velocity for 34 s and then power is shut off. The wheel slows down uniformly at 2.8 rad/s2 until the wheel stops. In this situation, the time interval of deceleration is closest to:
5) A machinist turns the power on to a grinding wheel, at rest, at time t=0 s. The wheel accelerates uniformly for 10 s and reaches the operating angular velocity of 96 rad/s. The wheel is run at that angular velocity for 40 s and then power is shut off. The wheel slows down uniformly at 1.5 rad/s2 until the wheel stops. In this situation, the time interval of deceleration is closest to:

QUESTION 1 A machinist turns off the power on a grinding wheel that is operating at an angular speed of 96 rad/s. The wheel slows down uniformly at 1.5 rad/s2 until it stops. Calculate the time it takes the wheel, in seconds, to come to a stop. Do not type in units.
the answer is D but I don't understand why.
please show work and explain how to get that answer

At time t=0 a grinding wheel has an angular velocity of 22.0 rad/s . It has a constant angular acceleration of 29.0 rad/s2 until a circuit breaker trips at time t = 2.10 s . From then on, the wheel turns through an angle of 436 rad as it coasts to a stop at constant angular deceleration. (a) Through what total angle did the wheel turn between t=0 and the time it stopped? Express your answer in radians. (b) At...
