Answer:
12.5r + 200 = 12.5*2r
Step-by-step explanation:
<h3>Given</h3>
Rate of Hoppertunity = r
Rate of Dortmund = 2r as it is twice as fast
<h3>Solution</h3>
Let the distance Hoppertunity runs be d, then the distance Dortmund runs is d + 200 m
Since it took 12.5 seconds Dortmund to catch Hoppertunity, it can be expressed as:
- d = 12.5r for Hoppertunity
- d + 200 =12.5*2r for Dortmund
<u>By replacing d in the second equation, we get:</u>
<u>Soving</u>:
- 12.5r = 200
- r = 200/12.5
- r = 16 m/sec
Hoppertunity's rate is 16 m/sec
Dortmund's rate is 32 m/sec
Answer is (45-25s^2)/(9s^2+6s-45)
the distance between the 2 points is 10
Answer:
11.37 lb-ft
Step-by-step explanation:
We are given that
Force,F=3 pounds

Let Point A (3,7) and point B(8,8)
We have to find the work done by the force.

feet
We know that Work done by the force

Substitute the values

Hence, the work done by the force =11.37 lb-ft
