1. A block of mass m=100kg rests on a level ground. With what force, parallel to the ground, must you push the block so that it is just ready to start sliding? The coefficient of static friction between the block and the ground is 0.40.

  1. Force required = (mass)*g*(mus)

    where mus is the static friction coefficient and g is the acceleration of gravity. Use SI units for the force in Newtons
