An object with a mass of m= 15 kg is at rest on a frictionless surface and is subject to 2 forces acting upon it. The first force is directed in the negative x direction with a magnitude of F1. The second force has a magnitude of F2 and acts on the body of the object at an angle 0-25° measured from the horizontal. L 3 F₁ Write an expression for the component of net force, in the x direction in terms of the variables given. Write an expression for the magnitude of the normal force acting on the object in terms of F2 and the other variables given. Assume the surface it rests on is rigid. If the two forces change such that F1-8.5 N and F2- 18.75 N the object may no longer be in equilibrium, find the objects acceleration in the x direction in meters per second squared.
