Question

The maximum speed with which a car can be driven round a curve of radius 18m without skidding (g=10m/s^2 and coefficient of friction between tyres and road is 0.2 is

Answer 1

Answer:

6 m/s

Explanation:

v=√urg

so u=coefficient of friction =0.2

r=18m/s²

so v=√(0.2)18(10)

v=√36

v=6m/s
