Problem 20E

Problem 20E

A toy train rolls around a horizontal 1.0-m-diameter track. The coefficient of rolling friction is 0.10.

a. What is the magnitude of the train’s angular acceleration after it is released?

b. How long does it take the train to stop if it’s released with an angular speed of 30 rpm?

Step-by-Step Solution:

Solution 20E

Step 1 of 5

For the given tran toy, which performs uniform circular motion around a diameter  with the coefficient of rolling friction . Here we need to calculate the magnitude of the angular acceleration of train . Also, we need to calculate the stopping time of train if the train is released with initial speed of .

Given data,

Diameter,

Radius,

Coefficient of friction

Initial speed,

Using

                                

                                        

To find,

  1. Angular acceleration,
  2. Stopping time,
