Please show work

c) (5 pts) Find the centripetal acceleration of the car. d) (5 pts) What is the speed of the car? 4) (20 pts) A 1 000 kg car drives around a 200-m radius flat curve on a rainy day when the coefficient of static friction between its tires and the road is 0.500. It travels around the curve as fast as possible without sliding. a) (5 pts) Draw a free body diagram from the car. Pretend You are at street level and viewing the car from behind as it goes around the curve. b) ( 5 pts) Find the normal force on the car.

a) Fc = mv^2/r <--------O--------> f = u*m*g

b) N = mg = 1000*9.8 = 980 N

c) a = u*g = 0.5*9.8 = 4.9 m/s^2

d) v^2/R = a

V = 31.3 m/s
