A Hockey puck of a mass 350g is sliding along the ice at 6.0 m/s[n] when it hits a rough patch of ice that exerts a frictional force of 0.42N(adsbygoogle = window.adsbygoogle || []).push({});

i)Determine the pucks acceleration

ii)determine how far the puck will slide before stopping.

f=ma a=f/m a=.42/.35 this gives me 1.2 or something but it is slowing down therefore it should a negative, should I rewrite the equation givingaa negative value or is there a better equation for the information given.
