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

it also supports my hypothesis. if you rest first you can squeeze the clothespin more times. from the data i collected the average of the eight people concluded exercise makes your muscles more fatigued and less able to squeeze the clothespin compared to resting before squeezing.

the farther away the object is from the central star (the sun) it's gravitainal pull on the object is weaker when it is farther
