A) A bicycle wheel of radius r = 0.5 m starts from rest and rolls 150 m without slipping in 30 s. Calculate
a) the number of revolutions the wheel makes,
b) the number of radians through which it turns,
c)The average angular velocity.
B) Assuming that the angular acceleration of the wheel given above was constant, calulate:
a) the angular acceleration,
b) the final angular velocity,
c) the tangential velocity and tangential acceleration of a point on the rim after one acceleration.
