Onward to calculations! s#2: A wheel that makes 800 rev/min slows down to 500 rev/min while making a total of 60 evolutions (but.. we don't work in rev/min... we need radis). a. Find the correct units(rad/s) for w; & wf, and find the angular displacement, 0, in grad. b. What is the angular acceleration during this time frame? C. How long does it take the wheel to slow down to 500rev/min? d. Find the linear speed of an object that is located 35 cm from the center of the wheel when the wheel is spinning at 500 rev/min. Qs#3: The angular acceleration of a wheel is 4 rad/s?. If the wheel is initially at rest, how many revolutions does the wheel do in the 1st 8.0 seconds? Qs#4: A wheel is rotating at 4.0 rad/s & accelerates at +0.25 rad/s?. So... Given: wi =4 rad/s a=0.25rad/s? At= 38 a. What is the angular displacement in radians during the first 3 seconds? b. What is the angular velocity at the END of the 3 seconds? c. If an object is located 40 cm from the center of the wheel, what linear distance did that object travel during the 3-second time interval
