(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

a sled slides along a horizontal surface on which the coeffient of kinetic friction 0.25. its veocity at pt A is 8m/s at pt B its 5m/s. use impulse-momentum theorem to find how long the sled takes to travel from A to B

2. Relevant equations

P=J

3. The attempt at a solution

m(delta)v=Ft

(delta)v=ukgt

vf-vi=ukgt

uk = kinetic friction coeff.

ive gotten this far and im not sure how i'm suppoes to solve for time if theres 2 unknown varibles g and t.. is there a way i can solve for g .

am i doing this question correctly?
