A person 1.90 m tall walks on a horizontal icy surface. The coefficient of friction between the surface of the ice and the person's shoe sole is μ = 0.33 and the length of the person's legs are 1/2 of the person's height. Determine the maximum step length the person can make without slipping forward.

Hint: When walking, a person's weight is evenly distributed on each leg. Express the components of the weight in terms of the angle of walking produced by the person's legs and equate the horizontal component of this force to the force of friction acting at the contact between each sole and the horizontal icy surface.

I have no idea how to do this prob.
