Question

A car starting from 5m/s acquires a velocity of 10m/s in 2s .Calculate the acceleration.​

Answer 1

Answer:

U =5m/s

v =10m/s

time=2second

Explanation:

According To the Formula

a=(v-u)/t

a=((10-5)m/s)/2second

a=5/2m/s²

or 2.5m/s²

Answer 2

initial velocity=u=5m/s

Final velocity=v=10m/s

Time=t=2s

We know

$\boxed{\sf Acceleration=\dfrac{v-u}{t}}$

$\\ \rm\longmapsto Acceleration=\dfrac{10-5}{2}$

$\\ \rm\longmapsto Acceleration=\dfrac{5}{2}$

$\\ \rm\longmapsto Acceleration=2.5m/s^2$
