How much centripetal force (in N) is required to keep an object with mass 2.5kg moving uniformly in a circle of radius 0.33m at a constant linear speed of 1.7m/s?

490 n  f=125n a=2.5m/s2

At maximum height, kinetic energy is converted in potential energy  formula: at max height, ke = ½ * 0.27kg * (16m/s) ² = 34.56 j  so the remaining pe = (41.70 – 34.56)= 7.14 j = 0.27 kg * 9.8m/s² * h  = (9.8/7.14 * 0.27)so max height h = 5.08 or 5 m
