here,
the rotational speed , w = 3600 rpm
w = 376.8 rad/s
time t = 2.1 s
B)
from part a)
alpha = 180 rad/s^2
let the angle be theta
theta = u0*t + 0.5 * alpha * t^2
theta = 0 + 0.5 * 180 * 2.1^2
theta = 396.9 rad
n = theta/2pi = 63.2 revolution
the number of revolutions are 63.2

The tub of a washer goes into its spin-dry cycle, starting from rest and reaching an angular speed of 3.7 rev/s in 6.3 s. At this point the person doing the laundry opens the lid, and a safety switch turns off the washer. The tub slows to rest in 7.8 s. During the whole process of starting up and stopping, through how many revolutions does the tub turn? Assume constant angular acceleration while it is starting and stopping. Answer in...
