Answer #1

Work done in carrying a mass against gravity is given by, , where, is the work done, is the mass of object, is the vertical height acheived and is the acceleration due to gravity.

Given,    = 70 kg + 32.1 kg = 102.1 kg

   = 11.8 m

Known, = 9.81 m/s2

Work done,

Thus, the total work that would be done is 11818.89 Joules

In the image of the wheelbarrow below, the woman is applying a force with her hands in the vertical direction. If we assume that the wheelbarrow has a weight of 50N and the bag of soil has a weight of 175N, how much force will she have to apply to hold it steady? Please calculate to 2 decimal places. Be sure to select the correct units.

Consider the energy we use everyday in routine tasks, where that energy comes from, and where it goes. When you climb stairs you overcome the force of gravity to raise yourself to some height. It does not matter what the slope of the stairs are; the work done is against gravity which is always vertical so only the height counts. Take a typical human mass of 65 kg (roughly 143 lb of gravitational pull or weight) and a stairway up...

Context Students researching backpack weights gathered data from 45 elementary school children in the 3rd and 5th grades. The variable is “percent of body weight carried in the school backpack.” So a child who weighs 60 pounds and carries 9 pounds has a variable value of 15% (9 ÷ 60 = 0.15 = 15%). The American Chiropractic Association...
