An 85 kg object is moving at a constant speed of 15 m/s in a circular path, which has a radius of 20 meters. What centripetal force is exerted on the body?

a. 63.75 NB. 765.00 NC. 956.25 ND. 42.50 N

The answer is : 956.25 N Fc = Centripetal Force, m = mass, V i = velocity and r is radius Fc = [m * (V) ²] : r Fc = [85 kg * (15 m/s) ²] : 20 m Fc = [85 kg x 225 m²/s²] : 20 m Fc = 19,125 kg•m²/s² : 20 m Fc = 956.25 kg•m/s² or 956.25 N
