(b) A car is stopped in a horizontal road. The car weighs 4500N and its center of gravity C is 40cm behind the front wheels axle and 80cm in front of the rear wheels axie. Find the normal force on each tyre. (C) Considering the centripetal force for a car moving on a banked track (or road). Show that for a given velocity, V and radius, r, the angle of inclination of the track (or banking angle) is = tan-¹). (Hint: R₁ and R₂ are the normal reactions of the wheels; 0= angle of the curved track or road). SECTION C 5 (a) Two circles in a plane, C₁ and C₂, each rotate with frequency o (relative to the inertial frame) as shown below. The center of C, is fixed in an inertia frame. The center of C₂ is fixed on C₁. A mass is fixed on C₂. The position of the mass relative to the center C, is R(t). Find the fictitious force felt by the mass. (b) 6.
