A body moves in a straight line for which graph of $v_{x}$ vs x is shown in the graph. Find the magnitude of acceleration of the body at $x = 3 m$ .

Answer:

2.00

Solution:

From given graph

$v = - x + 5 for 1 \leq x \leq 4.$

So, $\frac{dv}{dx} = - 1$ or, $(\frac{vdx}{dx})_{x = 3} = - 2$

∴ magnitude of acceleration

$= 2 m / s^{2}$
