Question

what will be the final velocity of a vehicle, if it started from rest and accelerates at 4m/s² after 5 seconds?​

Answer 1

v = 20 m/s

Step-by-step explanation:

Let's use v = u + at for uniform acceleration.

v = finaly velocity

u = initial velocity

a = acceleration

t = time

Since we start from rest, our initial velocity is zero.

`v = 0 + 4(5)`

`v = 20 m/s`
