Question

Georgia is jogging with a velocity of $4m/s$ when she accelerate at $2m/s^2$ for $3$ seconds. How fast is Georgia running now?

Answer 1

Given,

Initial velocity, $u=4m{s}^{-1}$

Acceleration, $a=2m{s}^{-2}$

Time, $t=3\sec$

Apply equation of kinematic, for final velocity $V$

$v=u+at$

$v=4+2\times 3=10m{s}^{-1}$

Hence, velocity after $3\sec$ is $10m{s}^{-1}$
