However I thought I must use. F = -ma??

Would it be simply Force - frictional force 250-196= 54 F=ma 54 = 50a a = 54/50 This equals 1.08 m/s^2 in my first answer

Then using a=v^2-u^2/2s I come to 1.08m/s^2

Completely agree on insight, but I'm struggling atm, just a bit of back ground, I'm not a maths or physics student, I'm doing a career change atm and have to study mechanical principle at this level, we have to go through so many topics that I have to admit I very rarely understand the topics we...

Homework Statement Just asking for a little help on this question 50kg object is pulled across a rough horizontal surface with a uniform force of 250N for 15m from rest, the surface has a frictional coefficient of 0.4, calculate the acceleration using dealemberts principle But this results in...
