A 3 kg mass is subjected ti multiple forces and remains motionless. The gravitational force pulls the mass downward. a rope pulls the mass at an angle of 37degrees with respect to the positive x direction with a force of 7N. a person applies a force of 11N at angle of 143degrees with respect to the positive x direction on the mass. Lastl, a constant force acts on the mass keeping it at rest.

a. What's the direction and magnitude of the contact force?

b. If the contact force is removed, what magnitude and direction of acceleration is produced?

c. What change in potential energy occurs 7.21 seconds after the contact force is removed, relative to when the contact force was present?
