Aperson is pulling on a block of mass m with a force equal to its weight directed 30 above the horizontal plane across a rough surface, generating a friction 'f' on the block. if the person is now pushing downward on the block with the same force 30 degrees above the horizontal plane across the same rough surface, what is the friction on the block?
a) f
b) 1.5f
c) 2f
d) 3f

Orque can be calculated by multiplying the force (n) applied at 90∘ to the lever arm at a distance (m) from the pivot point (point of rotation), the compound si unit for the torque is n⋅m. if the force (at 90∘ to the lever arm) applied is 15 n and it is applied at 2.0 m from the pivot point (point of rotation), what is the torque on the lever?
