In a Laundromat, during the spin-dry cycle of a washer, the
rotating tub goes from rest to its maximum angular speed of 8.70
rev/s in 6.80 s. You lift the lid of the washer the instant the
angular speed reaches the maximum value, and notice that the tub
decelerates and comes to a stop in 13.5 s. Assuming that the tub
rotates with constant angular acceleration while it is starting and
stopping, determine the total number of revolutions undergone by
the tub during this entire time interval.

The tub of a washer is in a spin-dry cycle, running at a
constant angular speed of 77 rad/s for a duration of 10s. After
10s, the lid is opened and the safety switch turns off the washer.
The tub slows down to rest in 5s. Find the total angular
displacement (for entire 15s) in
(a) radians =

A ballerina does a spin. a) Strating from rest, she accelerates
to an angular velocity of 15.7 radians per seconds in 1.2 seconds.
she maintains velocity for 1.0 more seconds. How far does she turn
in total? Give your answer in number of rotation
b) As she spins she is balanced on an area of her shoe with
diameter 3.0cm. Here center of gravvity is located 2.5 feet above
the ground and in the equilibrium postion is centered horizontally.

A basketball is dropped from 140 meters height with back spin.
It goes straight down and then it gains speed as it curves 70
meters horizontally away from where it is dropped. That is a
spectacular example of the Magnus effect. A paper cylinder is
dropped down the inclined plane and rolls backward. This is another
example of Magnus affect. Why is the example of the basketball more
extreme than that of the paper cylinder ?

During a Tatooine speeder race, Dannik Jerriko starts from rest
and accelerates constantly for a time T, reaching a speed of 50
m/s. He then gives his engine to Garindan to use in his speeder,
which (including the engine) is twice the mass of Dannik’s speeder.
If Garindan also starts from rest and accelerates constantly, how
fast will he be going after the same amount of time T?

A wheel, starting from rest, rotates with a constant angular
acceleration of 1.40 rad/s2. During a certain 6.00 s
interval, it turns through 36.6 rad. (a) How long
had the wheel been turning before the start of the 6.00 s interval?
(b) What was the angular velocity of the wheel at
the start of the 6.00 s interval?
