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 1.0 kg block is initially at rest on a bench. It is pushed a distance 5.0 m with a force of 50 N. The coefficient of kinetic friction between the block and the benchtop is 0.30 What is the energy dissipated by friction? A) 10 J B) 15 J C) 20 J D) 25 J E) 30 J
1. A 4-meter plank weighing 8 kg is lying on a dock with 2.71 meters of its length on the dock, and the rest of its length extending off the dock. If a child weighing 61.2 kg walks out onto the part of the plank extending off the dock, what is the maximum distance in meters that the child can walk on the plank from the edge of the dock before he falls into the water? 2. A man pulls...
Finding distance and displacement from g Position (meters) 10조 8 Time (seconds) What is the displacement of the iguana between 0s and 5 s? What is the distance traveled by the iguana between 0 s and 5 s?
A car travels 88 meters north and 96 meters east. What is the distance traveled by the car in meters?
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.
8. (10 pts) Given a crate of mass 2000 kg: a. How much work is done in raising the crate 6 meters above the floor? b. What will the crate's potential energy be at that height:

A 15kg object falls a distance of 5.0 meters. How much work does gravity do on the object during this motion? Use the work-energy principle (from chapter 6- NO POTENTIAL ENERGY) to determine the speed of the object just as it reaches the ground. Assume there is no air resistance and the object starts from rest.
