Answer:
F = 592238.09 N
Explanation:
To find the mean force you first calculate the acceleration by using the following kinematic equation:
![v^2=v_o^2+2ax\\\\v_o=0m/s\\\\v=10km/h\\\\x=8.4m\\\\](https://tex.z-dn.net/?f=v%5E2%3Dv_o%5E2%2B2ax%5C%5C%5C%5Cv_o%3D0m%2Fs%5C%5C%5C%5Cv%3D10km%2Fh%5C%5C%5C%5Cx%3D8.4m%5C%5C%5C%5C)
you do "a" the subject of the equation and replace the values of the other parameters:
![a=\frac{v^2}{2x}=\frac{10000m/s}{2(8.4m)}=595.23\frac{m}{s^2}](https://tex.z-dn.net/?f=a%3D%5Cfrac%7Bv%5E2%7D%7B2x%7D%3D%5Cfrac%7B10000m%2Fs%7D%7B2%288.4m%29%7D%3D595.23%5Cfrac%7Bm%7D%7Bs%5E2%7D)
next, the force, by using the second Newton law is:
![F=ma=(1000kg)(595.23\frac{m}{s^2})=595238.09\ N](https://tex.z-dn.net/?f=F%3Dma%3D%281000kg%29%28595.23%5Cfrac%7Bm%7D%7Bs%5E2%7D%29%3D595238.09%5C%20N)
hence, the force is 592238.09 N

você faz "a" o assunto da equação e substitui os valores dos outros parâmetros:
Em seguida, a força, usando a segunda lei de Newton, é:
portanto, a força é 592238.09 N
Answer:
The total distance is 105 kilometers, and the total displacement is 15 kilometers east.
Explanation:
A truck moves 60 km east and then 45 km (60 - 15) back to west. The total distance will be,
Distance = 60 + 45 = 105
Distance is a scalar quantity that refers to the total space covered by a truck (object).
Displacement is a vector whose length is the shortest distance from the initial to the final position of a point undergoing motion.
The truck moves from Point A to Point B, covers 60 km. Then the truck turns back from point B to point C, 15 km away from the point A. So the displacement will be
Displacement = 60 - 45 = 15
Displacement is the difference between point A and C.
For further understanding, see the attached picture.
Answer:
Apparent frequency increases for Bob and decreases for Jill.
Explanation:
Doppler effect refers to the apparent change in frequency when there is relative motion between source and the listener. When the source and listener move closer, the apparent frequency heard by the listener increases. And when the source and listener move away from each other, the apparent frequency heard by the listener decreases.
Thus, when the emergency vehicle approaches Bob, the apparent frequency of the siren increases. It moves away from Jill, the apparent frequency heard by the Jill decreases.
