Question

The coefficient of friction between the tyres and road is 0.4. The maximum speed of a car round a curve of
radius 100 m is (g = 10 ms2)
1)20 m/s 2) 25 m/s 3) 30 m/s 4) 15 m/s

Answer 1

Explanation:

4) 15 m/s

hope it helps you....kkkkfz

Answer 2

Answer:

Fc = umg

u = friction

mv^2/r = ugm

g and m are cancelled

hence

v = √ umr

v = √ 400

v= 20
