1. A 45kg block is being pulled at a 25 degree angle on a
surface by a force F. Assume that the static friction (μstatic) of
the surface is 0.1 and the kinetic friction (μkinetic) is 0.03.

and determine the minimum force F to get the block moving. What is
the magnitude of the blocks acceleration once it starts to move if
the force is maintained?
