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

Answer:

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

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 :

$v=u+at$

$v=at$

$v=5\ m/s^2\times 6\ s$

v = 30 m/s

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