Acertain ball has the property that each time it falls from a height h onto a hard, level surface, it rebounds to a height rh, where 0 < r < 1. suppose that the ball is dropped from an initial height of h meters. (a) assuming that the ball continues to bounce indefinitely, find the total distance that it travels. (b) calculate the total time that the ball travels. (use the fact that the ball falls 1 2 gt2 meters in t seconds.)

Why is there friction between objects

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.
