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

my coursework is to analyse data i have been given the mass on a hanger and acceleration of a trolley on an incline. the incline is there to counteract friction and the mass of the trolley is 995g. the trolley was accelerated by taking masses from on the trolley and adding them to a hanger pulling the trolley.

i have also been gven an extension of the coursework were i have the mass on the trolley and the acceleration but this time the mass on the trolley increased at the mass on the hanger remained at 200g. the mass of the trolley itself is still 995g

2. Relevant equations

i would like to know how i calculate the resultant force

3. The attempt at a solution

i am not sure if i find the weight for the 1st experiement and this will give then force. and do i use f = ma for the second experiement.
