Question

a). A bicycle wheel has an initial angular velocity of 1.50 rads/s. If its angular acceleration is 0.300 rad/s^2, through what angle has the wheel turned from t = 2.50 s to t = 5.00 s?

	a.	3.7500 rads
	b.	6.5625 rads
	c.	11.2500 rads
	d.	4.6875 rads

Answer 1

Given:

initial angular velocity of the wheel,

angular acceleration of the wheel,

initial time span,

final time span,

Using equation of motion for the first time interval:

Using equation of motion for the second time interval:

Now the angular displacement between the two given time interval:

OPTION: b.
