...and pedal cranks 17.5 cm long. The cyclist pedals at a steady angular rate of 79.5 rev/min. The chain engages with a front sprocket 15.2 cm in diameter and a rear sprocket 6.00 cm in diameter.
(a) Calculate the speed of a link of the chain relative to the bicycle frame.
m/s
(b) Calculate the angular speed of the bicycle wheels.
rad/s
(c) Calculate the speed of the bicycle relative to the road.
m/s
(d) What pieces of data, if any, are not necessary for the calculations? (Select all that apply.)
-length of pedal cranks
-diameter of rear sprocket
-diameter of front sprocket
-angular rate
-diameter of wheels
-none of these
Please show equations and work used to get the answers you got. Thanks
