8. A 1000 kg car travels from point A topoint B, rounding the turn of radius 70meters with a constant speed of 60 km/hr.a. What is the acceleration for the car?b. How long does it take the car to get from point A to point B if the turn spans 90"?c. What is the force of friction between the car and the road that is necessary for the car tocomplete the turn?m29. At the right is an overhead view of twomasses, m1 = 3 kg and m2 = 2 kg, that areconnected to a central post by cords. Bothrotate about the post with the same period of3.0 seconds. The horizontal surface on whichmlthey rest is frictionless with r1 = 10 cm and r2= 20 cm. Determine the tension in each cord.
