Question

The tub of a washer goes into its spin-dry cycle, starting from rest and reaching an angular speed of 4.0 rev/s in 7.0 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 12.0 s. Through how many revolutions does the tub turn during this 19 s interval? Assume constant angular acceleration while it is starting and stopping.

_____rev

Answer #1

The tub of a washer goes into its spin-dry cycle, starting from
rest and reaching an angular speed of 2.0 rev/s in 8.0 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 12.0 s.
Through how many revolutions does the tub turn during this 20-s
interval? Assume constant angular acceleration while it is starting
and stopping. rev

The tub of a washer goes into its spin-dry cycle, starting from
rest and reaching an angular speed of 7.0 rev/s in 8.0 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 13.0 s.
Through how many revolutions does the tub turn during this 21 s
interval? Assume constant angular acceleration while it is starting
and stopping. rev

The tub of a washer goes into its spin-dry cycle, starting from
rest and reaching an angular speed of 4.0 rev/s in 8.0 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 11.0 s.
Through how many revolutions does the tub turn during this 19 s
interval? Assume constant angular acceleration while it is starting
and stopping.

The tub of a washer goes into its spin-dry cycle, starting from
rest and reaching an angular speed of 4.0 rev/s in 13.0 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 14.0 s.
Through how many revolutions does the tub turn during this 27 s
interval? Assume constant angular acceleration while it is starting
and stopping.

The tub of a clothes washer goes into its spin-dry cycle
starting from rest and reaches an angular speed of 4.70 rev/s in
7.03 seconds. At this point, the person doing the laundry opens the
lid, and a safety switch turns off the washer. The tub then slows
to a stop in 20.04 seconds. Assuming a constant angular
acceleration, while the tub is starting and stopping, how many
revolutions does the tub turn during this 27.07 second
interval?

The tub of a washer goes into its spin cycle, starting from rest
and gaining angular speed steadily for 8.00 s, at which time it is
turning at 6.00 rev/s. At this point, the person doing the laundry
opens the lid, and a safety switch turns off the washer. The tub
smoothly slows to rest in 9.00 s. Through how many revolutions does
the tub turn while it is in motion? rev

In a laundromat, during the spin-dry cycle of a washer, the
rotating tub goes from rest to its maximum angular speed of 9.7
rev/s in 8.8 s. You lift the lid of the washer and notice that the
tub decelerates and comes to a stop in 18.5 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 washing machine goes into its spin cycle, starting from
rest and gaining angular speed steadily for 8.00 s, at which time
it is turning at 4.00 rev/s. At this point, the lid of the washing
machine is opened, and a safety switch turns it off. The tub then
smoothly slows to rest in 13.0 s. Through how many revolutions does
the tub rotate while it is in motion?

The tub of a washer is in a spin-dry cycle, running at a
constant angular speed of 50 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 and (b)
revolutions?

A top-loading washing machine has a cylindrical tub that rotates
about a vertical axis. The tub of one such machine starts from rest
and reaches an angular speed of 5.0 rev/s in 8.0 s. The lid of the
machine is then opened, which turns off the machine, and the tub
slows to rest in 12.0 s. Through how many revolutions does the tub
turn during this 20 s interval? Assume constant angular
acceleration while it is starting and stopping.
