2.Motion in Straight Line
normal
Refer to the graph in figure. Match the following
A$(A \rightarrow r, B \rightarrow q, C \rightarrow s, D \rightarrow p)$
B$(A \rightarrow q, B \rightarrow r, C \rightarrow s, D \rightarrow p)$
C$(A \rightarrow r, B \rightarrow s, C \rightarrow q, D \rightarrow p)$
D$(A \rightarrow r, B \rightarrow q, C \rightarrow p, D \rightarrow s)$
Solution
(a)
We have to analyse slope of each curve i.e. $\frac{d x}{d t}$. For peak points $\frac{d x}{d t}$ will be zero as $x$ is maximum at peak points.
For graph $(A)$, there is a point $(B)$ for which displacement is zero. So, a matches with $(r)$.
In graph $(B)$, $x$ is positive $\diamond 0$ ) throughout and at point $B_1, V=\frac{d x}{d t}=0$
since, at point of curvature changes $a=0$, So $b$ matches with $(q)$
