An old-fashioned (vinyl) record rotates at a constant rate of 33 rpm.

(a) What is its angular speed in rad/s?
rad/s

(b) If the record has a radius of 9 cm, what is the linear speed of a point on its edge?
m/s

Expert Solution

Given data

constant rate =33rpm

angular speed(w)= 33(2pie/60)

=33(2)(3.14)/60

=3.454 rad/sec

(b) liner speed v=rw

r=0.09m

v=0.09*3.454

=0.31086m/s

A ladder rotates at a constant rate of w rad/sec as its top end slides down a vertical wall and its bottom end slides along the ground. A beetle sleeping on the ladder stays a meters from the top and b meters from the bottom. Find the speed of the beetle relative to the ground at the moment the ladder makes an angle of theta radians with the ground.

Starting from rest, a disk rotates about its central axis with constant angular acceleration. In 4.00 s, it rotates 13.2 rad. During that time, what are the magnitudes of (a) the angular acceleration and (b) the average angular velocity? (c) What is the instantaneous angular velocity of the disk at the end of the 4.00 s? (d) With the angular acceleration unchanged, through what additional angle (rad) will the disk turn during the next 4.00 s?

1) For a first-order reaction, after 230s, 33% of the reactants remain. Calculate the rate constant for the reaction. 2) A compound decomposes with a half-life of 80s and the half-life is independent of the concentration. How long does it take for the concentration to decrease to one-ninth of its initial value?

A horizontal circular platform rotates counterclockwise about its axis at the rate of 0.977 rad/s. You, with a mass of 73.3 kg, walk clockwise around the platform along its edge at the speed of 1.09 m/s with respect to the platform. Your 21.1-kg poodle also walks clockwise around the platform, but along a circle at half the platform\'s radius and at half your linear speed with respect to the platform. Your 18.5-kg mutt, on the other hand, sits still on...
