Question

21.
The following table gives the data about motion of a car.

Answer 1

Explanation:

If you have ever been on an amusement park ride that travels in a curved or circular path, then you have experienced a force, called a centripetal force, pushing you into the ride. Whether it's the back wall of the "Roundup" or "Rotor", the ride where the floor drops from beneath your feet, or the seat belt of the "roller coaster" that supplies the force, you are constantly being accelerated toward the ride's center of curvature.
