The tub of a washer goes into its spin-dry cycle, starting from rest and reaching an angular speed of 5.0 rev/s in 8.0 s. at this oint, the person doing the laundry open the lid, and a safety switch turns off the washer. the tub slows to rest in 12.0 s. thru how many revolutions does the tub trun during the entire 20-s interval? assume constant angular acceleration while it is starting and stopping.

The total number of revolution is 50 rev.

Explanation:

Given that,

Angular speed = 5.0 rev/s

Time = 8.0 s

We need to calculate the angular acceleration

Using equation of angular motion

Put the value into the formula

We need to calculate the angular displacement

Using equation of angular motion

Put the value into the formula

Now, The washer coming to rest from top spin

We need to calculate the angular acceleration

Using equation of angular motion

We need to calculate the angular displacement

Using formula of displacement

Put the value into the formula

We need to calculate the total number of revolution

Hence, The total number of revolution is 50 rev.
