Question

The drive propeller of a ship starts from rest and accelerates at 2.9 x 10-3 rad/s2 for 2.4 x 103 s. For the next 4 x 103 s the propeller rotates at a constant angular speed. Then it decelerates at 6 x 10-3 rad/s2 until it slows (without reversing direction) to an angular speed of 6 rad/s. Find the total angular displacement of the propeller.

Answer #1

The drive propeller of a ship starts from rest and accelerates
at 3.00 x 10-3 rad/s2 for 2.47 x 103 s. For the next 1.61 x 103 s
the propeller rotates at a constant angular speed. Then it
decelerates at 2.34 x 10-3 rad/s2 until it slows (without reversing
direction) to an angular speed of 2.35 rad/s. Find the total
angular displacement of the propeller.

The drive propeller of a ship starts from rest and accelerates
at 2.1 x 10-3 rad/s2 for 2.1 x 103 s. For the next 2 x
103 s the propeller rotates at a constant angular speed. Then it
decelerates at 2 x 10-3 rad/s2 until it slows (without
reversing direction) to an angular speed of 7 rad/s. Find the total
angular displacement of the propeller.

The drive propeller of a ship starts from rest and accelerates
at 2.1 x 10-3 rad/s2 for 2.1 x 103 s. For the next 2 x
103 s the propeller rotates at a constant angular speed. Then it
decelerates at 2 x 10-3 rad/s2 until it slows (without
reversing direction) to an angular speed of 7 rad/s. Find the total
angular displacement of the propeller.

The drive propeller of a ship starts from rest and accelerates
at 2.44 x 10-3 rad/s2 for 2.48 x 103 s. For the next 1.08 x 103 s
the propeller rotates at a constant angular speed. Then it
decelerates at 2.84 x 10-3 rad/s2 until it slows (without reversing
direction) to an angular speed of 2.93 rad/s. Find the total
angular displacement of the propeller.

The drive propeller of a ship starts from rest and accelerates
at
2.90 × 10−3 rad/s2 for 2.10 × 103 s. For the next 1.40 × 103 s the
propeller rotates at a constant
angular speed. Then it decelerates at 2.30 × 10−3 rad/s2 until it
slows (without reversing direction)
to an angular speed of 4.00 rad/s. Find the total angular
displacement of the propeller.

A helicopter propeller blade starts from rest and experiences a
constant angular acceleration of 18.0 rad/s2. Find the speed of a
point on the blade 2.35 m from the axis of rotation when the blade
has completed 18 revolutions.

What is the angular displacement of a wheel that accelerates
from rest to 6 rad/s with an angular acceleration of 2
rad/s2?

1. A wheel starts from rest and has an angular acceleration of
6.00 rad/s2 . When it has made 3.00 rev its angular
velocity in rad/s is:
2. A circular disk of radius 1.00 m rotates, starting from rest,
with a constant angular acceleration. What is the centripetal
acceleration of a point on the edge of the disk at the instant that
its angular speed is 2.50 rev/s?

An electric vehicle starts from rest and accelerates at a rate
of 2.1 m/s2 in a straight line until it reaches a speed
of 19 m/s. The vehicle then slows at a constant rate of 1.3
m/s2 until it stops. (a) How much time
elapses from start to stop? (b) How far does the
vehicle move from start to stop

An electric vehicle starts from rest and accelerates at a rate
of 1.9 m/s2 in a straight line until it reaches a speed of 22 m/s.
The vehicle then slows at a constant rate of 1.2 m/s2 until it
stops. (a) How much time elapses from start to stop? (b) How far
does the vehicle move from start to stop?
