M1 question- Resolving frictional forces
I am having a problem with this question, and was wondering whether I could have a bit of a nudge in the correct direction?
I cannot do part 'iv'; however, I think that I may have worked out part iv for question iii though Im not sure
The answers I have so far are:
Fmax= Coefficient of friction x R:
Any help is greately appreciated concerning parts iii and iv
