Question

Calculate the velocity of a car (in m/s) that starts from rest and accelerates at 5 m/s^2 for 6 seconds.

Answer 1

The final velocity of the car is 30 m/s.

Step-by-step explanation:

Given that,

Initial speed of the car, u = 0

Acceleration of the car,
`a=5\ m/s^2`

Time taken, t = 6 s

Let v is the final velocity of the car. It can be calculated using first equation of kinematics as :

`v=u+at`

`v=at`

`v=5\ m/s^2* 6\ s`

v = 30 m/s

So, the final velocity of the car is 30 m/s. Hence, this is the required solution.
