Question

The position x, in meters, of an object is given by the equation:

Answer 1

Answer:

The SI units of A, B and C are :

$m,\ m/s\ and\ m/s^2$                  

Explanation:

The position x, in meters, of an object is given by the equation:

$x=A+Bt+Ct^2$

Where

t is time in seconds

We know that the unit of x is meters, such that the units of A, Bt and $Ct^2$ must be meters. So,

• $A=m$

• $bt=m$

$b=\dfrac{m}{s}=m/s$

• $Ct^2=m$

$C=m/s^2$

So, the SI units of A, B and C are :

$m,\ m/s\ and\ m/s^2$

So, the correct option is (B).
