What work is involved in bench pressing 90.7 kg a distance of .8 meters?
work = force*distance
=mass x gravity x distance
=90.7 x9.8 x0.8
=711.088 joules
What work is involved in bench pressing 90.7 kg a distance of .8 meters?
A weight lifter is bench-pressing a barbell whose weight is 710 N. He raises the barbell a vertical distance of 0.65 m, and then lowers it back to its original position next to his chest. Assume the weight is raised and lowered at a constant velocity, and that “up” is the positive direction. Determine the work done on the barbell (a) While the barbell is being raised (b) While the barbell is being lowered
Which required more work: lifting uniformly a 50.0 kg crate a vertical distance of 2.0 meters or lifting a 25.0 kg crate a vertical distance of 4.5 meters with a 1.0 m/s^2 acceleration?
Show work, please!

A tension force pulls a block a distance 96 meters along a frictionless, horizontal floor. The block has a mass of 10 kg. If the tension force has a magnitude of 91 Newtons, and is oriented at 20-degrees above the horizontal, what was the work done by the tension force? Give the numerical answer in Joules.
shevon (58 kg) is performing a bench-step test. she performs the test three times, once on a box that is 41.3 cm (16.25 in.) high, once on a box that is 50 cm (19.7 in.) high, and once on a box that is 21 cm (8.26 in.) high. if she performed the bench step with exactly the same step rate (22 steps ∙ min−1) with each of the different box heights, what would happen to her heart rate response? what...
