How do tires to increase the friction between the tire and the road?

The de broglie relation λ=h/p can be rewritten in terms of the wave number k as p=kℏ. recall that wave number is defined by k=2π/λ. using the fact that λ=v/f, find the wave numbers k1 and k2 corresponding to frequencies f1 and f2. express your answer as two expressions

Aball has an initial velocity of 3 m/s. if there is no friction, what is the highest it could roll?
