Traveling at a speed of 18.5 m/s, the driver of an automobile suddenly locks the wheels by slamming on the brakes. the coefficient of kinetic friction between the tires and the road is 0.630. what is the speed of the automobile after 1.25 s have elapsed? ignore the effects of air resistance.

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.
