Problem 34E
Section 4.7 Nonuniform Circular Motion and Angular Acceleration
A bicycle wheel is rotating at 50 rpm when the cyclist begins to pedal harder, giving the wheel a constant angular acceleration of 0.50rad/s2.
a. What is the wheel’s angular velocity, in rpm, 10 s later?
b. How many revolutions does the wheel make during this time?

QUESTION:
Problem 34E
Section 4.7 Nonuniform Circular Motion and Angular Acceleration
A bicycle wheel is rotating at 50 rpm when the cyclist begins to pedal harder, giving the wheel a constant angular acceleration of 0.50rad/s2.
a. What is the wheel’s angular velocity, in rpm, 10 s later?
b. How many revolutions does the wheel make during this time?
ANSWER:
Step 1 of 4
The objective here is to first determine the final angular velocity of a bicycle wheel, whose initial angular velocity, the time interval and the angular acceleration is known. Further, we need to determine the number of revolutions of the wheel in the given time interval.
