Two forces Fa and Fb are applied to an object whose mass is 8.0kg. The larger force is Fa. When both forces point due east the object's acceleration has a magnitude of 0.50m/s^2. However, when Fa points due east and Fb points due west, the acceleration is 0.40 m/s^2, due east. Find the magnitude of Fa and the magnitude Fb.
If you would, you'd have a lot more success... I'll start you off for the first scenario: |dw:1344314173309:dw| Now do Newton's 2nd law on that...
Do the fbd for the second scenario and Newton's second again and you should have a system of equations to solve for Fa and Fb.
i already got the answer. Thank you :)
please close the question then.
