Question

A vehicle moving with uniform acceleration of 2m/s^2 has a velocity of 4m/s at a certain time. What will its velocity be 5s later

Answer 1

We have v=u+at,so v or final velocity will be 4+2*5=14 m/s

Answer 2

$\bf{\underline{\underline{Question:-}}}$

• a vehicle moving with a uniform acceleration of 2m/^2 has a velocity of 4m/s at a certain time. What will it's velocity be at: 5 second later

$\bf{\underline{\underline{Given:-}}}$

Uniform acceleration (a) = 2m/sec²

velocity (u) = 4 m/sec

$\bf{\underline{\underline{Find:-}}}$

velocity after 5 sec ?

$\bf{\underline{\underline{we \:know:-}}}$

• First equation of motion v = u + at

$\bf{\underline{\underline{Solution:-}}}$

$\rm → v= u+at$

$\rm → v = 4+2×5$

$\rm → v=4+10$

$\rm → v=14$

$\bf{\underline{\underline{Hence:-}}}$

• Velocity after 5 sec is 14m/sec
