1.) Calculate the work done in lifting a 200 N couch a distance of 1.3 m from a loading ramp.
2.) How much work is done when a 40 N force is applied to push a shopping cart a distance of 6 m?
3.) Calculate how much work you would have to do to push your car (which has a mass of 254 kg) a
distance of 3 meters

Explanation:

work = force ×distance

1 w = ? f= 200 d= 1.3

w = f ×d

=200×1.3

= 269 joule

2 w=? f=40. d=6

w= 40/6

= 240 joule

3. w=? m=254. f= ? d=3

w=f=mg. f= 254×10. f= 2540

w=f×d

=2540×3

= 7620 joule

Explanation:

1) to calculate the workdone in lifting a 200N cough a distance of 1.3m from a loading lamp

our workdone = ?

Force = 200N

Distance = 1.3 m

from the formula of workdone

W = F × D

work done  = 200 × 1.3

workdone  = 260 joules

2) workdone = ?

Force = 40 N

Distance = 6m

workdone = force × distance

W = 40 × 6

Workdone = 240 joules

3) workdone = ?

mass = 254kg

distance = 3m

workdone = force × distance

force = mg

f= 254 × 9.8

F  = 2489.2 N

workdone  = force  × distance

workdone = 2489.2 × 3

workdone =  7467.6 joules

the answer would most likely be c, because if it's a comical piece of information, it may likely not be true, if it's a site that allows anybody to edit the content, it could mean a five year old is typing the info, and if it's a tv show produced by a celeb, it may have a biased opinion.
