i need part b:
If at this instant, the wheel starts to slip, find the value of the
STATIC coefficient of friction.
The center O of the 2-kg wheel has an initial velocity vo 0.3 m/s down the 15 incline. The wheel has a radius of gyration of 60 mm about O. A force F-10N is applied to the cord wrapped around the inner hub. If the wheel rolls without slipping, calculate the velocity v of the center O when...

A bicycle wheel has four firecrackers attached to it on opposite ends of the wheel's diameter, as shown in the figure to the right. When the firecrackers are lit, they release heated gas away from their front ends. The bicycle wheel is pivoted against a wall by its center of mass and is free to spin. a. Which way will the bicycle wheel spin when the firecrackers are lit? Explain using the torque right hand rule. b. What is the...

A 12.0 kg object is attached to a cord that is wrapped around a
wheel of radius 10.0 cm. The acceleration of the object down the
frictionless incline is measured to be 2.00 m/s2. Assuming the axis
of the wheel to be frictionless, determine a) the tension in the
rope, b) the moment of inertia of the wheel, and c) the angular
speed of the wheel 2.00 s after it begins rotating, starting from
rest.
