Question

When the road is dry and the coefficient of friction is µ , the maximum speed of a car in a circular path is 10 m/s, if the road becomes wet and µ µ ′ = / 2 . What is the maximum speed permitted?

Answer 1

Answer: 10√22=5√2m/s.

Explanation:

• When the road is dry and the coefficient of friction is mu, the maximum speed of a car in a circular path is 10 m/s. if the road becomes wet and mu'=(mu)/(2), what is the maximum speed permitted? i.e., 10√2 or 10√22=5√2m/s.
