That is true Step by step:
The horizontal and vertical components of a projectile's velocity are independent of each other.
Answer: Option C
<u>Explanation:</u>
The path of a projectile is determined by two components of motion. They are termed as horizontal and the vertical components. Since both components velocity are perpendicular to each other, so it can stated that they are independent of each other.
Even it can seen that when the horizontal components of velocity is constant, then there will be change in the vertical components of velocity leading to free fall projectile path.
And in the absence of gravity, there will be change in the horizontal components of velocity with zero vertical component of velocity. Thus, the horizontal and the vertical components of a projectile’s velocity are seemed to be independent of each other.
Answer:
The acceleration of the car will be ![a=9600m/sec^](https://tex.z-dn.net/?f=a%3D9600m%2Fsec%5E)
Explanation:
We have given that distance from stop sign s = 200 m
Time t = 0.2 sec
We have to find the constant acceleration
Now from second equation of motion ![s=ut+\frac{1}{2}at^2](https://tex.z-dn.net/?f=s%3Dut%2B%5Cfrac%7B1%7D%7B2%7Dat%5E2)
![200=40\times 0.2+\frac{1}{2}\times a\times 0.2^2](https://tex.z-dn.net/?f=200%3D40%5Ctimes%200.2%2B%5Cfrac%7B1%7D%7B2%7D%5Ctimes%20a%5Ctimes%200.2%5E2)
![a=9600m/sec^](https://tex.z-dn.net/?f=a%3D9600m%2Fsec%5E)
So the acceleration of the car will be ![a=9600m/sec^](https://tex.z-dn.net/?f=a%3D9600m%2Fsec%5E)
Answer:
<em>Magnitude of the Frictional force is 200 N</em>
Explanation:
The frictional force is the force that tries to oppose relative motion between two surfaces that are contacting. The coefficient of static friction is the coefficient of friction of a body that is not moving.
Newton's third law of motion states that action and reaction forces are equal and opposite. So the frictional force felt on the filing cabinet will be equal to the applied force pulling the cabinet.
Frictional force = Force applied
Force applied = 200 N
Therefore, the magnitude of the friction force on the filing cabinet is 200 N
