Question

Multiple Correct Answers Type:
The figure shows the velocity (v) of a particle plotted against time (t)

• A. The particle changes its direction of motion at some point
• B. The acceleration of the particle remains constant
• C. The displacement of the particle is zero
• D. The initial and final speeds of the particle are the same

Answer 1

Answer: (A), (B), (D)

The correct options are
A The particle changes its direction of motion at some point
B The acceleration of the particle remains constant
D The initial and final speeds of the particle are the same

From the figure, Area of $\left(\Delta AOD\right)$=Area($\Delta ABC)$=$\frac{1}{2}\times T\times V_0$

Net area $=\frac{V_{0}T}{2}-\frac{V_{0}T}{2}=0$

Displacement =0

'V' vs 't' graph is constant.

$a=\frac{dv}{dt}=$constant

Direction of velocity changes.

particle changes its direction of motion

In graph,initial and final speed are same
