Atrain starts from rest and accelerates uniformly until it has traveled 2.1 km and acquired a forward velocity of the train then moves at a constant velocity of for 400 s. the train then slows down uniformly at until it is brought to a halt. the distance traveled by the train while slowing down is closest to a train starts from rest and accelerates uniformly until it has traveled 2.1 km and acquired a forward velocity of the train then moves at a constant velocity of for 400 s. the train then slows down uniformly at until it is brought to a halt. the distance traveled by the train while slowing down is closest to 3.8 km. 4.2 km. 3.6 km. 4.4 km. 4.0 km.

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.
