    Coefficient of Friction of a baseball player

    Question: A baseball player slides into third base with an initial speed of 8.35 m/s. If the coefficient of kinetic friction between the player and the ground is 0.36, how far does the player slide before coming to rest? How would I start this problem?? I would use Ff=uFn but it doesn't even...

    Calculate Frictional Forces Needed for 6.5kg Shopping Cart on 13° Incline

    I have a question.. A shopper pushes a 6.5kg shopping cart up a 13 degree incline, heading east. Find the magnitude of the horizontal force, F, needed to give the cart an acceleration of 1.61 m/s2 (seconds squared). This is what I have done. sigmaFx= F(what I'm trying to find) - Fg,x - Ff...
