A dragster starts from rest and accelerates down a track. Each tire has a radius of 0.320 m and rolls without slipping. At a distance of 352 m, the angular speed of the wheels is 268 rad/s. Determine (a) the linear speed of the dragster and (b) the magnitude of the angular acceleration of its wheels.The two-gear combination shown in the figure is being used to hoist the load L with a constant upward speed of 2.50 m/s. The rope attached to the load is being wound onto a cylinder behind the big gear. The depth of the teeth of the gears is negligible compared to the radii. Determine the angular velocity (magnitude and direction) of (a) the larger gear and (b) the smaller gear. 0.300 m 0.170 m " = 2.50 m/'sA bicycle wheel of radius 0.70 m is rolling without slipping on a horizontal surface with an angular speed of 2.0 rev/s when the cyclist begins to uniformly apply the brakes. The bicycle stops in 5.0 5. Through how many revolutions did the wheel rotate during the 5.0 seconds of braking
