Atractor drags a 300 lb. concrete block 80 ft. in 120 seconds. determine the power output of the tractor.
2400 ft-lb/sec
300 ft-lb/sec
200 ft-lb/sec
120 ft-lb/sec

For this case we have that by definition, the mechanical power is given by:

Where:

W: It is the work done

t: It's time

For its part:

Where:

F: It is the applied force

d: It is the distance traveled

According to the data we have that the drag force of the tractor is , while the distance traveled is

Substituting:

Finally, the power is:

Option C

answer: b)

step-by-step explanation:

its a dot plot because since the score is not high numbers.
