Answer:
Acceleration, [tex]a=2\ m/s^2[/tex]
Explanation:
It is given that,
A car moving south speeds up from 10 m/s to 40 m/s in 15 seconds.
It means,
Initial velocity of the car, u = 10 m/s
Final velocity of the car, v = 40 m/s
Time taken, t = 15 seconds
We have to find the acceleration of the car. Mathematically, acceleration of the car is given by taking difference in velocities divided by time taken i.e.
[tex]a=\dfrac{v-u}{t}[/tex]
[tex]a=\dfrac{40\ m/s-10\ m/s}{15\ s}[/tex]
[tex]a=2\ m/s^2[/tex]
Hence, this is the required solution.
