## Homework Statement

So i did a lab in school this week and i have to write a report but i am having some problems getting friction. so i have two masses a 1703 gram block and a hanger that pulls the block that has 700 grams on it. The block went a distance of 45cm in a time of .41 seconds. i have to get the tension and friction of it

## Homework Equations

i used S=1/2(a)t^2

i also know i am supposed to use T-fk=m1*a and t-m2*g=m2*a i think

## The Attempt at a Solution

i used the first formula for the acceleration and i got 5.354 m/s^2and after this i tried finding the tension in the string and i got 3.1122 N which i am not completely sure is correct but the main problem is i cannot find the friction i tried but i keep getting answers over 1 or negative answers and i am stuck. i might have done the lab wrong and gotten wrong weights or something but i am not sure.
