Respuesta :
it should be A. 2 m/s² because the equation for acceleration is ( final− initial) / Time so you must subtract 10 from 40 and you'll get 30 then you divide by 15 to get your answer 2.
Answer:
The acceleration of the car is 2 m/s².
A is correct.
Explanation:
Given that,
Initial velocity =10 m/s
Final velocity =40 m/s
Time = 15 sec
The acceleration is the rate of change of velocity.
The acceleration of the car is
Using equation of motion
[tex]v = u+at[/tex]
Here, v = final velocity
u = initial velocity
t = time
[tex]40=10+a\times15[/tex]
[tex]a = \dfrac{30}{15}[/tex]
[tex]a = 2\ m/s^2[/tex]
Hence, The acceleration of the car is 2 m/s².
