Question

Find the maximum speed at which a car can turn round a curve of 36 m radius on a level road.given the coefficient of the friction between the tyre and the road is 0.53

Answer 1

Answer:

Frictional force= centrifugal force

fmg=

r

mv

2

By substituting the values in the above equation we get

v

max

=

μgr

0.11=

9.8×30

v

2

Hence the maximum velocity is

5.68m/s
