Question

A force of 49n is just able to move a block of 10kg of wood on a rough horizontal surface calculate coefficient of friction and static friction

Answer 1

As its given that a 49N force is sufficient to move the block it is known that when 49N is applied the block just starts moving that means the limiting static friction must be equal to 49N so

friction (limiting) = normal reaction x "mu"

49 = 100 (inthis case, as mass is 10 kg) x "mu"

mu = 0.49

but dude this is the case when angle of force applied is 180 degrees to the friction.........
