The position, x, of an object is given by the equation x = A + Bt +Ct2, where t refers to time. What are the dimensions of A, B,

Serjik [45]

Answer: Dimensions of A are of length [L]

Dimensions of B are of $LT^{-1}$

Dimensions of C are of $LT^{-2}$

Step-by-step explanation:

The given equation is

$x(t)=A+Bt+Ct^{2}$

Since the dimension on the L.H.S of the equation is [L] , each of the terms on the right hand side should also have dimension of length[L] to be dimensionally valid

Thus

Dimensions of A = [L]

Dimensions of Bt = [L]

$Bt=[L]\\\\$ $[B][T]=[L]$ $\\\\\therefore [B]=LT^{-1}$

Similarly

Dimensions of $Ct^{}2 = [L]$

$Ct^{2}=[L]\\\\[C][T]^{2}=[L]\\\\\therefore [C]=LT^{-2}$

Question 31 (Essay Worth 5 points)

arsen [322]

For this case we have by definition, that the derivative of the position with respect to time is the velocity, that is to say:

$\frac {d (s (t))} {dt} = v (t)\\\frac {d (6-14t)} {dt} = v (t)$

So:

Taking into account that the derivative of a constant is 0.

$\frac {d (6-14t)} {dt} = 0- (1 * 14 * t ^ {1-1}) = 0- (14 * t ^ 0) = - 14$

So, the velocity is -14

Answer:

-14
