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

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

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
