1. A horse walks 90 m on a circular track of radius 100m. Relative to the center of the track, what angle was covered? (in radians). - A 1200 kg car traveling at 10 m/s skids to a stop in 2 s. What is the magnitude of the average frictional force required to stop the car? a A stick with moment of interia 10 kg-m” is pivoted about one end with a 5 N force applied 0.4 m from the pivot. What is the stick's angular acceleration? What is the frequency, in cycles/second, of a 6-kg object oscillating on a spring of stiffness 50N/m. 8) A mechanic tightens a bolt 90 degrees with a 10 cm long wrench and 5 N force on its end. а How much work did he do?
