Answer : The acceleration of the car is, [tex]5m/s^2[/tex]
Explanation :
By the 1st equation of motion,
[tex]v=u+at[/tex] ...........(1)
where,
v = final velocity = 20 m/s
u = initial velocity = 5 m/s
t = time = 3 s
a = acceleration of the car = ?
Now put all the given values in the above equation 1, we get:
[tex]20m/s=5m/s+a\times (3s)[/tex]
[tex]a=5m/s^2[/tex]
Therefore, the acceleration of the car is, [tex]5m/s^2[/tex]
