Two friends, joe and sam, go to the gym together to strength train. they decide to start off with an exercise called flat bench press. lying flat on a bench with their arms in an extended position, they slowly lower (to their chest) and then raise a barbell back to the starting position. they start off by using a 45.0 kg barbell. joe is taller than sam which means joe\'s arms are 69.4 cm long while sam\'s are 60.6 cm. calculate the work done by joe, wjoe, when he raises the barbell to finish one repetition. the acceleration due to gravity is 9.81 m/s3

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.
