Explanation:
directly
it is directly proportional
I know one reason and that is because they can be bias
Answer:
Work done by the frictional force is ![3.41\times 10^5\ J](https://tex.z-dn.net/?f=3.41%5Ctimes%2010%5E5%5C%20J)
Explanation:
It is given that,
Mass of the car, m = 1000 kg
Initial velocity of car, u = 26.1 m/s
Finally, it comes to rest, v = 0
We have to find the work done by the frictional forces. Work done is equal to the change in kinetic energy as per work - energy theorem i.e.
![W=k_f-k_i](https://tex.z-dn.net/?f=W%3Dk_f-k_i)
![W=\dfrac{1}{2}m(v^2-u^2)](https://tex.z-dn.net/?f=W%3D%5Cdfrac%7B1%7D%7B2%7Dm%28v%5E2-u%5E2%29)
![W=\dfrac{1}{2}\times 1000\ kg(0^2-(26.1\ m/s)^2)](https://tex.z-dn.net/?f=W%3D%5Cdfrac%7B1%7D%7B2%7D%5Ctimes%201000%5C%20kg%280%5E2-%2826.1%5C%20m%2Fs%29%5E2%29)
W = −340605 J
or
![W=3.41\times 10^5\ J](https://tex.z-dn.net/?f=W%3D3.41%5Ctimes%2010%5E5%5C%20J)
Hence, the correct option is (a).
Inches, feet, yards, meters
