A 10 kg object is subjected to two forces F1 and F2. F1 has a magnitude of 20 N and acts straight upward and F2 has a magnitude of 30 N at 30 degrees below the horizontal from the positive x axis. a) Find the acceleration of the object.
b) A third force F3 is applied so that the object is in static equilibrium. Find F3.

Aboxcar traveling at 12 m/s approaches a string of 5 identical boxcars sitting stationary on the track. the moving boxcar collides and links with the stationary cars and they all move off together along the track. what is the final speed of the cars immediately after the collision? (you may take the mass of each boxcar to be 18,537 kg.)
