The solution of the problem 1.8 cr 1 from the problem b

Task 1.8
The material point moves along a circle whose radius is 20 m. The dependence of the path traversed by the point on time is expressed by the equation s = t3 + 4t2-t + 8. Determine the distance traveled, the angular velocity and the angular acceleration of the point in 3 seconds from the beginning of its movement.
