A baseball player slides into third base with an initial speed of 8.45 m/s.
If the coefficient of kinetic friction between the player and the ground is 0.40, how far does the player slide before coming to rest?

How do I begin to solve this problem?

he lsaides until the woprk done against friction equals the initial kinetic energy.

M*g*(0.40)*X = (1/2) M V^2

X = (0.5/0.4) V^2/g = 1.25 V^2/g
