Calculate the work done. a tractor pulls a heavy log with a force of 100 pounds. the log moves 3 feet.

1,000 ft-lbs
3,000 ft-lbs
130 ft-lbs
300 ft-lbs

300 ft-lbs

Step-by-step explanation:

For work like this,

Just multiply 100 times 3.

You always just multiply the two numbers

Example:

Calculate the work done.

A crane lifts 5,000 newtons to the top of a roof which is 6 meters high.

3,000 ft-lbs

30,000 Nm

5,000 Nm

300 Nm

5,000 x 6 = 30,00

it can also be done like this

5 x 6 = 30

+ 00 = 30,00

answer: what are the answer choices?

step-by-step explanation:

step-by-step explanation:

given that ab is divided into equal parts as

ac, cd, de, ef, fg, gh, hi, ib.

from this we find that f is the midpoint of ab.

so using mid point formula we find

f = (3,7)

similarly considering fb, we get

h = mid point of fb = ((6,6) and g, mid point of fh is

g = (9/2, 13/2)

i is mid point of hb

so i =(15/2,11/2)
