Answer:
The SI units of A, B and C are :
Explanation:
The position x, in meters, of an object is given by the equation:
![x=A+Bt+Ct^2](https://tex.z-dn.net/?f=x%3DA%2BBt%2BCt%5E2)
Where
t is time in seconds
We know that the unit of x is meters, such that the units of A, Bt and
must be meters. So,
![b=\dfrac{m}{s}=m/s](https://tex.z-dn.net/?f=b%3D%5Cdfrac%7Bm%7D%7Bs%7D%3Dm%2Fs)
![C=m/s^2](https://tex.z-dn.net/?f=C%3Dm%2Fs%5E2)
So, the SI units of A, B and C are :
![m,\ m/s\ and\ m/s^2](https://tex.z-dn.net/?f=m%2C%5C%20m%2Fs%5C%20and%5C%20m%2Fs%5E2)
So, the correct option is (B).
