amusement park ride rotates around a fixed axis such that the angular position of a point on the ride follows the equation: θ(t) = a + bt2 – ct3 where a = 2.1 rad, b = 0.75 rad/s2 and c = 0.035 rad/s3. a. Determine an equation for the angular speed of the ride as a function of time, omega(t). Write your answet using the symbols a, b, and c, instead of their numerical values. b. Besides at t = 0, at what time t1 is the ride stopped? Give your answer in seconds. c. What is the magnitude of

Nilo.p A baseball bat is swung with an angular velocity of 500°/s and has a radius of 1.2m. What is the linear velocity of the baseball bat?

A strap, rod, or something comparable is used to spin up the disc.  I imagine someone hand-starting a lawnmower. If he pulls the strap with a final speed before pulling the strap away, what is the rotation rate of the disk, ω in rev/s?  The moment of inertia of a disc is 1/2MR2.  There's no sliding. Strap's final speed = v = 0.99 m/s. The disc's radius is R = 0.3 m The disc's mass is M = 0.8 kg
