1). A bicyclist notesthat the pedal sprocket has a radiusof r_p = 12 cm while thewheel sprocket has a radiusof r_w = 5.5 cm. The twosprockets are connected by a chain which rotates without slipping.The bicycle wheel has aradius R = 63 cm. When pedaling thecyclist notes that the pedal rotates at one revolutionevery t = 1.5 s. When pedaling, thewheel sprocket and the wheel move at the same angular speed.

Part (b) Calculate the angular speedof the pedal sprocket ?_p, in radians persecond.

Part(c) Calculate the linear speed of the outeredge of the pedal sprocket v_p, incentimeters per second.

v_p =

Part(d) Calculate the angular speed of the wheelsprocket ?_w, in radians persecond.

?_w =

Part(e) Calculate the linear speed of thebicycle v, in meters per second, assuming the wheeldoes not slip across the ground.

v =

17% Part(f) If the cyclist wanted to travel at a speedof v₂ = 4.5 m/s, how muchtime, in seconds, should elapse as the pedal makes one completerevolution?

t₂ =
