Unformatted text preview: evenly spaced. What minimum speed must the arrow have? Problem 5: A cyclist starts from rest and pedals such that the wheels of his bike have a constant angular acceleration. After 13 .0 s, the wheels have made 62 rev. (a) What is the angular acceleration of the wheels? (b) What is the angular velocity of the wheels after 13.0 s? (c) If the radius of the wheel is 35 .0 cm, and the wheel rolls without slipping, how far has the cyclist traveled in 13.0 s? Problem 6: The flywheel of a steam engine runs with a constant angular speed of 143 rev/min. When steam is shut off, the friction of the bearings and the air brings the wheel to rest in 1 .9 h. (a) What is the magnitude of the constant angular acceleration of the...
