A 10. kilogram wood box is at rest on a wood floor.  When a horizontal force is applied on the box toward the right, the box begins to gain speed at a constant, steady rate.  After a period of 5.0 seconds, the box has attained a velocity of 20. m/s.  What is the magnitude of the applied force?

Click the game tab at the bottom of the simulation and select level 1. (there is no seesaw balance for this part of the activity.) balance the first equation, and click check to see if you got it right. if you can’t balance it in the first try, you can try again. work through the five equations for level 1. click continue to go on to level 2, and later level 3. each level is more difficult than the one before. keep trying until all the equations are balanced. in one or two sentences, describe how you did in the balancing game. in a few more sentences, explain one strategy you learned for balancing more complex equations.
