The graph of an object's motion (along the $x -$ axis) is shown in the figure. The instantaneous velocity of the object at points $A$ and $B$ are $v_{A}$ and $v_{B}$ respectively. Then

Options:

Answer:

Solution:

Instantaneous velocity $v = \frac{Δ x}{Δ t}$ From graph, $v_{A} = \frac{Δ x _{A}}{Δ t _{A}} = \frac{4 m}{8 s} = 0.5 m / s$ and $v_{B} = \frac{Δ x _{B}}{Δ t _{B}} = \frac{8 m}{16 s} = 0.5 m / s$ i.e., $v_{A} = v_{B} = 0.5 m / s$
