Three forces are exerted on an object and as a result the object moves with a constant velocity.One force is 60 N along the +x-axis, the second is 75 N along a direction making a counterclockwise angle of 150 with the +x-axis.
 
  (a) What is the magnitude of the third force? (b) What is the direction of the third force, measured clockwise from the +x-axis?

Question 2

A 100-N force has a horizontal component of 80 N and a vertical component of 60 N. The force is applied to a cart on a level frictionless floor. The cart starts from rest and moves 2.0 m horizontally along the floor due to this force.
 
  What is the cart's final kinetic energy?
  A) 160 J B) zero C) 120 J D) 200 J
