(a) A particle is moving along the x axis and its velocity vs position graph is as shown. Is the acceleration of the particle increasing, decreasing or remains constant?

(b) A particle is moving along x axis and its velocity (v) vs position (x) graph is a curve as shown in the figure. Line APB is normal to the curve at point P. Find the instantaneous acceleration of the particle at `x = 3.0 m`.

A

x - component of its velocity must be positive

B

x - component of its velocity must be negative

C

it may be speeding up

D

it may be slowing  down

Text Solution

Verified by Experts

The correct Answer is:
C
Direction of intial velocity can be same as that of the direction of acceleration. As result , it may be speeding up
