I just need to check if im right because the mark scheme is not available anymore on the exam board website. THanks.Quote:
A block of mass m kg is at rest on a horizontal plane. The coefficient of friction between the block and the plane is 0.2.
i) When a horizontal force of magnitude 5N acts on the block, the block is on the point of slipping. Find tht value of m.
ii) When a force of magnitude P N acts downwards on the block at angle X to the horizontal, as shown in the diagram, the frictional force on the block has magnitude 6N and the block is again on the point of slipping. Find P and X.
is this right? thanks!
