Answer:
The time is 0.6 sec.
Explanation:
Given that,
Acceleration of car = 7.2 m/s²
Speed = 4 m/s
We need to calculate the time
Using equation of motion
[tex]v=u+at[/tex]
Where, u = initial velocity
v = final velocity
a = acceleration
t = time
Put the value in the equation
[tex]4=0+7.2\times t[/tex]
[tex]t=\dfrac{4}{7.2}[/tex]
[tex]t=0.6\ sec[/tex]
Hence, The time is 0.6 sec.
