A 103kg baseball player slides into second base. Then coefficient of kinetic friction between the player and the ground is 0.607 a.) what is the magntiude of tfictional force? b.) if the player comes to rest after 2.22sec, what is his intial speed? a.) Fs max=Ms*Fn Ms=.607 Fn=103 0.607*103=62.521 but it's wrong b.) I thought could use V=Vo+At Vo=? V=O t=2.22 A=)Fk/m so 0=Vo+(Fk/m)*2.22 Is this the right set up?
