Chapter 6: Q6.1-2PE (page 221)

Microwave ovens rotate at a rate of about 6rev/min. What is this in revolutions per second? What is the angular velocity in radians per second?

Short Answer

Expert verified

It is 0.1 revolutions per second (rps).

The angular velocity is 0.628 rad/s.

Step by step solution

01

Definition of angular velocity

Angular velocity or rotational velocity, also known as angular frequency vector, is a pseudo vector representation of how rapidly the angular position or orientation of an item varies with time.

02

Calculation of the angular velocity

N=6revolutions per minute(rpm).

We know that1 min=60 sec.

So,the required revolution per minute (rps) can be calculated as follows:

=660=0.1

Therefore, the number of revolutions per second is 0.1 (rps).

The angular velocity can be calculated as:

=2π×0.1=0.628 rad/s

Therefore, the angular velocity is 0.628 rad/s.

In one amusement park ride, riders enter a large vertical barrel and stand against the wall on its horizontal floor. The barrel is spun up and the floor drops away. Riders feel as if they are pinned to the wall by a force something like the gravitational force. This is a fictitious force sensed and used by the riders to explain events in the rotating frame of reference of the barrel. Explain in an inertial frame of reference (Earth is nearly one) what pins the riders to the wall, and identify all of the real forces acting on them.

As a skater forms a circle, what force is responsible for making her turn? Use a free body diagram in your answer.

Modern roller coasters have vertical loops like the one shown in Figure. The radius of curvature is smaller at the top than on the sides so that the downward centripetal acceleration at the top will be greater than the acceleration due to gravity, keeping the passengers pressed firmly into their seats. What is the speed of the roller coaster at the top of the loop if the radius of curvature there is \({\bf{15}}.{\bf{0}}{\rm{ }}{\bf{m}}\) and the downward acceleration of the car is \({\bf{1}}.{\bf{50g}}\)?.

(a) Calculate Earth’s mass given the acceleration due to gravity at the North Pole is 9.830 m/s2and the radius of the Earth is 6371kmfrom pole to pole. (b) Compare this with the accepted value ofM=5.979×1024kg.
