CP Physics Circular Motion and Centripetal Force 1 2 ac ac Fc = mac F. = T T2 T = 1000 g = 1 kg 1 h = 3600 s 1 km = 1000 m 100 cm = 1 m (2) pAn object of mass 16.0 kg moves in a circle with a frequency of 216 min" (216 cycles per minute). As it does so, it experiences a centripetal force of 2048 N. Use the equations above to calculate the following values. You can go in any order you wish, but you must label your work, and include units in both the setup and the answer. (a) Calculate the object's centripetal acceleration, in m/s2. (b) Calculate the radius of the circle, in m, around which the object moves. (c) Calculate the object's speed around the circle in m/s
