A point mass of O.37 kg is set to rotate about a fixed axis 0.74 m away. The mass is initially at rest and undergoes a constant angular acceleration of 5.57 rad/s². At what time will the centripetal force acting on the mass be 55.4 N?

The following data measures a spinning mass at different angular speeds and the radial force (centripetal force) required to maintain its circular motion.  The mass always spins at a radius of: R = 5.14 cm   RPS Tangential Velocity (m/s) Force (N) 8.600   24.89 8.234   22.83 7.820   20.38 7.272   17.93 5.457   10.58 5.300   9.31 4.912   8.13 4.682   7.15 4.197   6.17 3.996   5.39 3.710   4.90 3.647   4.31 Convert from angular frequency to tangential speed

A 1.3 kg rock is swung in a circular path and in a vertical plane on a 1 m length string. At the top of the path, the angular velocity is 9 rad/s. What is the tension in the string at that point?

The royal antelope of western Africa has an average mass of only 2.5 kg. Suppose thisantelope runs in a circle with a radius of 35.0 m. If a force of 8.8 N maintains this circularmotion, what is the antelope’s tangential speed?
