A ball mass m is launched up a semicircular in a way that at the top of the chute, just before free fall, the ball has a centripetal acceleration of magnitude 6g. If the bottom of the chute is defined to be the height where the gravitational PE is 0 the moment the ball leaves the chute what is the mechanical energy?

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.
