What would, A cyclist starts from rest and pedals such that the wheels of his bike have a constant angular acceleration. b) What is its liner speed at t = 4.0 s? \\ What would have been the angular displacement of the engine: \, Just after a motorcycle rides off the end of a ramp and launches into the air, its engine is turning counterclockwise at 7425 rev/min. This is often caused by someone setting the clutch release too close to the end of the lever travel. A motorcyclist is traveling along a road and accelerates for 6.94 s to pass another cyclist. (Assume the acceleration and velocity have the same direction) (b) Thro, A car is traveling along a road, and its engine is turning over with an angular velocity of +199\ \mathrm{rad/s}. 18 miles per hour. After 10.0 s , the wheels have made 4.0 revolutions. What is the angle of inclination of the road to the nearest degree? Understand what is meant by rotational kinematics, and derive the rotational kinematic formulas. How far does a car travel horizontally when it travels 15m along the road? Incoming to rest, each wheel makes an angular displacement of +13.5 revolutions.
