Two turtles (each 1 kg) sit on an approximately massless stick balanced on a rock. They sit on opposite sides of the stick's center, each 2 m away. The stick (14 m long) is spinning at 4 rad/s about its center (nearly without friction) in the horizontal plane. Now, if both turtles walk to the far opposite ends of the stick: a.) What is the final angular speed of the stick turtles system

Answer: it will take   4.36 seconds to reach her average velocity 10.69 miles/hour.explanation:   we have equation of motion ,where s is the displacement, a is the acceleration, u is the initial velocity and t is the time taken.average velocity = displacement/ time taken.average velocity = 10.69 miles/hr = 10.69*1.6*1000/(60*60) = 4.75 m/s4.75 = s/ts = 4. 1we also have acceleration = 2.18 m/s², initial velocity = 0 m/sso it will take   4.36 seconds to reach her average velocity 10.69 miles/hour.
