Question

**If you were to climb a set of stairs that is 11.8 meters
high (in the vertical direction) with a 32.1kg backpack, how much
total work would you do (including your body weight and the
backpack)? Assume you have a mass of 70kg. Please calculate to 2
decimal places. Be sure to select the correct units.**

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/s ^{2}**

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...

A certain carnival game at the fair tests your strength by
asking you to swing a hammer and hit a spring. The further the
spring is compressed, the larger the prize you earn. A clever
physics student wants to win the largest prize at the fair and
observes that the spring must be compressed half a
meter in order to win the largest price. Please show work and
explain.
A) The student does experimenting and discovers that the spring
compresses...

Do the best you can with this one. Show all your work that
reaches the answer. The third part is not too easy and for that you
will have to think very carefully. A boat has a total mass,
including the load in it, of 200,000 kg (roughly a weight of 220
tons in our weight units). The boat is shaped like a barge, with a
length of 30 meters and a width of 15 meters. You may assume that...
