+ "50 ivkmtla 6. A 800 kg car is driving at speed v = 15 m/s across a circular depression with radius of curcvature of 50 m as shown. Friction and air drag are negligible. a. Draw a freebody diagram with vertical 50 m forces only for the car. All forces should be labeled as weights (w or Fg), normal forces in), kinetic friction forces (fk), static friction _fh forces (f5), or tensions (T). You do not need \\Q/ to include subscripts for the objects in this problem. You do not need to draw any horizontal forces on your diagram. (2 points) b. Find the magnitude of the normal force from the ground acting on the car. Show your work so that I can follow your logic. Correct answers that do not show work in a manner that I can follow will not receive full credit. (4 points)
