A 6.0 kg bowling ball is sliding (without rolling) at 5.0 m/s on a level floor when it hits one end of a horizontal spring. The opposite side of the spring is attached to a rigid wall. The spring compresses a distance of 0.77 m while stopping
the ball.
Which of the following most closely approximates the average force that the spring applies to the ball as it comes to
a stop?

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.
