a 14750 N car traveling at 57.0 kn/h rounds a curve of radius 2.00 x 10^2 m.?

Question

(a) Find the centripetal acceleration of the car. in (m/s^2)
(b) Find the force that maintains the centripetal acceleration (N)
(c) Find the minimum coefficient of static friction between the tires and the road that will allow the car to round the curve safely.

Answer 1

a) a=v^2/r
57 km/hr=15.83 m/s
a=15.83^2/200
a=1.25 m/s^2

b) F=m*a
F=14750*1.25/9.81
1879.46 N

c) m*g*µs=1879.46
µs=0.1274
