Question

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

Answer 1

Answer:

4 m/s²

Explanation:

Here, u = initial velocity = 0 m/s     [since it is at rest]

         v = final velocity = 20 m/s

         t = time = 5 s

$a = acceleration = \frac{v-u}{t} = \frac{20 \: m/s - 0 \: m/s}{5 \: s} = 4 \: m/s^2$
