The answer is B.
Temperature is just another term for the average kinetic energy of a substance.
Answer: F = 102141N
Explanation: <em><u>Newton's 2nd Law</u></em> states that a force can change the motion of a body. The relation is given by
F = m.a
whose units are:
[F] = N
[m] = kg
[a] = m/s²
Jenny's car, at the moment of the break, had acceleration:
![a=\frac{\Delta v}{\Delta t}](https://tex.z-dn.net/?f=a%3D%5Cfrac%7B%5CDelta%20v%7D%7B%5CDelta%20t%7D)
![a=\frac{11}{0.14}](https://tex.z-dn.net/?f=a%3D%5Cfrac%7B11%7D%7B0.14%7D)
a = 78.57 m/s²
Then, Force is
F = 1300*78.57
F = 102141 N
<u>Jenny's car experienced a force of </u><u>magnitude 102141N.</u>
I have all the answers here so take this
Answer:0.69
Explanation:
Coefficient of kinetic friction=f/R=61.8/90=0.69
Terminal velocity (Maximum velocity) is 9.8 meters a second. m/s.
If you wanted the exact answer, you would need the distance from the window to the ground; and than divide by 3.0. Otherwise, 9.8 meters a second would be your best bet.
