If the motorcycle can go from 0 to 50mph in 3 seconds the person is describing the motorcycle's acceleration.
Here we know that
now from kinematics we have
now from above all values we have
so final angular speed is -12.6 rad/s
If we are talking on the force being exerted by a segment of a rope of lenght R on the right on a point M which is being also pulled from the Left by a segment of rope R as shown in the figure attached. Then we invoke Newton's Third Law:
"Any force exerted by an object (in this case a segment of the rope) also suffers a equal and opposite force".
If we pick
whis is the tension exerted by the right segment then the left segment will also exert an equal and opposite force so we have that

Explanation:
ride. You estimate the radius of thebig wheel to be 15 {\rm m}, and you use your watch tofind that each loop around takes 25 {\rm s}.a.What is your speed
