slader At a carnival, you can try to ring a bell by striking a target with a 10.8-kg hammer. In response, a 0.408-kg metal piece is sent upward toward the bell, which is 4.23 m above. Suppose that 18.8 percent of the hammer's kinetic energy is used to do the work of sending the metal piece upward. How fast must the hammer be moving when it strikes the target so that the bell just barely rings

), in joules, must be equal to 18.8 percent of the translational kinetic energy of the hammer (
), in joules. 
(1)
(2)
- Mass of the metal piece, in kilograms.
- Gravitational acceleration, in meters per square second.
- Distance travelled by the metal piece, in meters.
- Mass of the hammer, in kilograms.
- Initial speed of the hammer, in meters per second. 
, 
, 
and 
, then the initial speed of the hammer is:

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.
