2.Motion in Straight Line

easy

At any instant, the velocity and acceleration of a particle moving along a straight line are $v$ and $a$. The speed of the particle is increasing if

A$v > 0, a > 0$

B$v < 0, a > 0$

C$v > 0, a < 0$

D$v > 0, a = 0$

Solution

(a)
For increasing speed both velocity $(v)$ and acceleration $(a)$ are in the same direction.
