Question

A car started from rest and moved along a straight road with constant acceleration of 2.0m/s-² for 6s.Calculate the speed of the car 6s after starting to move.​

Answer 1

The speed of the car 6 s after starting to move is 12 m/s.

Step-by-step explanation:

A car started from rest and moved along a straight road with constant acceleration of
`2\ m/s^2` for 6 seconds.

It is required to find the speed of the car 6 s after starting to move. Let v is the final speed of the car.

The relation between speed, acceleration and time is given by :

`v=u+at`

u = 0

`v=at\\\\v=2\ m/s^2* 6\ s\\\\v=12\ m/s`

So, the speed of the car 6 s after starting to move is 12 m/s.
