<h3><u>Answer;</u></h3>

= 2868 Newtons

<h3><u>Explanation;</u></h3>

Centripetal force is a force that acts on an object or a body in circular path and is directed towards the center of the circular path.

Centripetal force is given by the formula;

mv²/r ; where m is the mass of the body, r is the radius of the circular path and v is the velocity of a body;

mass = 65 kg, velocity = 15 m/s and r = 5.1 m

Therefore;

Centripetal force = (65 × 15²)/ 5.10

                            = 2867.65 Newtons

                            = 2868 N
