Problem
A steel crate rests on a smooth warehouse floor. Three horizontal forces already act on the crate: 18N toward the west, 10N toward the east and 7N toward the west.
(a) Calculate the resultant horizontal force acting on the crate due to these three forces and state its direction.
(b) Find the magnitude and direction of the smallest single additional horizontal force that must be applied to bring the crate into equilibrium.
(c) Suppose instead that a worker applies a 5N force toward the east. If the mass of the crate is 50kg, compute the magnitude of the acceleration produced and state its direction.
