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

b is 38 degrees.

a is 52 degrees.

this is because if b is 38 and a is 14 degrees more than b than 38+14=52 and 52+38=90 degrees. hope this .
