Abicycle has wheels of 0.8 m diameter. the bicyclist accelerates from rest with constant acceleration to 22 km/h in 11.6 s. what is the angular acceleration of the wheels?

α = 1.32 rad/s²

Explanation:

given,

diameter of the bicycle = 0.8 m

radius of the bicycle = 0.4 m

initial speed of the bicyclist,u = 0 m/s

final speed of the bicyclist,v = 22 Km/h = 22 x 0.278

                                           = 6.12 m/s

time,t = 11.6 s

acceleration =

                     =

                    =0.53 m/s²

we know,

    a = α r

  α = 1.32 rad/s²

the angular acceleration of the wheels is equal to α = 1.32 rad/s²

wind moving at higher speeds will transfer more energy to the water, resulting in stronger waves.
