Question

A bus start from rest. If the acceleration of the bus become 4m/s after 5second,calculate the final velocity of the bus.​

Answer 1

Correct Question:-

• A bus start from rest. If the acceleration of the bus is 4m/s² then after 5 seconds,calculate the final velocity of the bus.

To Find:-

• Find the velocity of the bus.

Solution:-

Here ,

• u = initial velocity

• v = final velocity

• a = acceleration

• s = distance

• t = time

Firstly ,

We have to find the final velocity of the bus:-

u = 0 ; a = 4m/s² ; t = 5 sec ; v = ?

Formula to be Used:-

$\tt\implies \: v = u + at$

$\tt\implies \: v = 0 + 4( 5 )$

$\tt\implies \: v = 20 m/s$

Hence ,

• Final velocity of bus is 20m/s.

Answer 2

So final velocity, v = 20m/s
