Fc=mv^2/r
Fc= 2000kg*(25m/s)^2/(80m) = 15625N
Hope this helps! Thank you!
Answer:
a) v = 141.9 m/s
b) v = 317.4 miles/h
Explanation:
a) How fast was he moving in meters per second?
![v = \frac{d}{t} = \frac{1000 m}{7.045 s} = 141.9 m/s](https://tex.z-dn.net/?f=%20v%20%3D%20%5Cfrac%7Bd%7D%7Bt%7D%20%3D%20%5Cfrac%7B1000%20m%7D%7B7.045%20s%7D%20%3D%20141.9%20m%2Fs%20)
Hence, the jet ski is moving at 141.9 meters per second.
b) How fast was he moving in miles per hour?
Therefore, the jet ski is moving at 317.4 miles per hour.
I hope it helps you!
All you have to do is add 600 + 1,400 which = 2,000
So your answer is D) 2,000 J
I hope this helps. :)
I had the same test btw
Answer:
<u>36 m</u>
Explanation:
We can consider this to be an AP.
Then,
<u>Subtract a₇ from a₉.</u>
- a + 8d - a + 6d = 24 - 20
- 2d = 4
- d = 2
<u>Finding a₁₅</u>
- a₁₅ = a + 14d
- a₁₅ = 8 + 14(2)
- a₁₅ = 8 + 28
- a₁₅ = <u>36 m</u>
