Question

If a Vehicle starts from rest attain uniform velocity 20m/s in 5 seconds Calculate
Its acceleration​

Answer 1

$we \: have \\ \: u = 0m/s \\ \: v = 20m/s \\ \: t = 5s$

$acceleration = \frac{v - u}{t}$

$= \frac{20 - 0}{5}$

$= \frac{20}{5} \\ = 4 {m/s}^{2}$

so,..acceleration is 4 metre per second square.
