In lacrosse, a ball is thrown from a net on the end of a stick by rotating the stick and forearm about the elbow. If the angular velocity of the ball about the elbow joint is 28.9 rad/s and the ball is 1.45 m from the elbow joint, what is the linear velocity v of the ball? v = m/s

A hamster running in a wheel of radius 15 cm spins the wheel at 23 revolutions per minute.   a)  What is the angular velocity of the wheel? (in radians/sec)            b)  At what linear velocity is the hamster running? (in cm/sec)

How long will it take to circle the island exactly 7 times?

A race car, starting from rest, travels around a circular turn of radius 28.5 m. At a certain instant, the car is still accelerating, and its angular speed-is 0.794 rad/s. At this time, the total acceleration (centripetal plus tangential) makes an angle of 35.0° with respect to the radius. What is the magnitude of the total acceleration? Number Units

A ferris wheel with a radius of 15 meters starts from rest and achieves it's maximum tangential speed of 2.4 meters per second in 33 seconds. What is the magnitude of the tangential acceleration

A particle moves 6.7 m along a circle of radius 2.0 m. (Enter the magnitudes.) (a) Through what angle does it rotate (in rad)?  rad (b) If the particle makes this trip in 1.0 s at a constant speed, what is its angular velocity (in rad/s)?  rad/s (c) What is its acceleration (in m/s2)?  m/s2

A diver runs horizontally off the end of a diving tower 3.5m above the surface of the water with an initial speed of 2.5 m/s. During her fall she rotates with an average angular speed of 2.6 rad/s How many revolutions has she made when she hits the water? Express your answer using two significant figures.Δθ= (?) rev
