5) A person pulls on a 50 kg desk w/ a 200N force acting at a 30Á angle above the horizontal. The desk does not budge.
a) Write the equation that describes the forces which act in the x-direction.
b) Write the equation that describes the forces which act in the y-direction.
c) Determine the x and y components of the force of tension.
d) Determine the values of the frictional and normal forces.
6) Suppose the person were PUSHING down at a 30Á angle with 200N of force. The desk still does not move.
a) Write the equation that describes the forces which act in the x-direction.
b) Write the equation that describes the forces which act in the y-direction.
