A 2kg object experiences two concurrent forces, f1=100N at 37 degrees above the positive x-axis and f2=80N at 53 degrees above the x-axis (sin37 and cos53=0.6, sin53 and cos37=0.8). Find 1. The component in the x-axis
2. Component in the y-axis
3. Resultant force
4. The direction of the resultant force
5. The acceleration of the body
