Work to lift each baby = (90N) x (1.0 meter) = 90 joules. Work to lift both of them =
2 x 90 joules = 180 joules

How much work does a mother do if she lifts each of her twin babies upward 1.0 m and each baby weighs 90 N?
Answer Expert Verified
Work to lift each baby = (90N) x (1.0 meter) = 90 joules. Work to lift both of them =
2 x 90 joules = 180 joules

How much work do you do to carry the sled if your house is 800 m away?
How much work do you do to carry the sled if your house is 800 meters away?
50 Joules to lift sled
and no work is done to carry the sled 9. An ant sits on the back of a mouse. The mouse carries the ant across the floor for a distance of 10 meters.
What are the two different units that represent work?
| Work | SI unit joule (J) | Other units Foot-pound, Erg | In SI base units 1 kg⋅m 2 ⋅s − 2 | Derivations from other quantities W = F ⋅ s W = τ θ |

How much work is done on a 300 Newton suitcase to lift it 0.50 meter?
Work done is force multiplied by distance, Hence work done is 300×0.50=
150 joules

What force are you working against when you lift a backpack?
The force you are applying is
upwards
. Since the backpack does not move upward as you walk horizontally you do no work on the object.
How do you calculate work done?
The formula for work is ,
work equals force times distance
. In this case, there is only one force acting upon the object: the force due to gravity. Plug in our given information for the distance to solve for the work done by gravity.
What is work measured in?
One joule
is defined as the amount of work done when a force of one newton is exerted through a distance of one meter. In the English system of units, where force is measured in pounds, work is measured in a unit called the foot-pound (usually abbreviated ft-lb).
How much work is required to lift a 2 kg mass to a height of 10 meters?
the Work done to life the mass of 2 kg to a height of 10 m is
196 J
.
Which of the following is the best explanation of work?
What is the best explanation of work?
Work occurs when a force acts on an object and causes a displacement of that object
.
How do u calculate force?
It is summarized by the equation:
Force (N) = mass (kg) × acceleration (m/s2)
. Thus, an object of constant mass accelerates in proportion to the force applied. If the same force is applied to two objects of differ- ent mass, the heavier object has less acceleration than the lighter object (Figure 1).
How much work is required to lift a 10 Newton?
In the diagram,
55 joules
of work is needed to raise a 10-newton 5.0 meters.
What is when a 5 kg mass is lifted from the ground to a height of 10 meters?
Question: When a 5-kilogram mass is lifted from the ground to a height of 10 meters, the gravitational potential energy of the mass is increased by
approximately Ca. 500J C6
