The time period of the simple pendulum is 2.4 seconds.
Given the data in the question;
- Time taken to swing from leftmost point to rightmost point;
- Period of the pendulum;
Period is the time needed for a complete cycle of vibration to pass a given point.
Period of a pendulum is the of time needed for it to complete one full back-and-forth motion. It is the time required to for the pendulum to swing from leftmost point to rightmost point and back to leftmost point.
Now, if it took the pendulum to swing from leftmost point to rightmost point, it will also take the pendulum
to swing back to its original position( leftmost point )
Hence,
= time taken to swing from leftmost to rightmost + time taken to swing from rightmost point to leftmost point.
Therefore, the time period of the simple pendulum is 2.4 seconds.

To solve this problem it is necessary to apply the concepts related to Normal Force, frictional force, kinematic equations of motion and Newton's second law.
From the kinematic equations of motion we know that the relationship of acceleration, velocity and distance is given by
Where,
Final velocity
Initial Velocity
a = Acceleration
x = Displacement
Acceleration can be expressed in terms of the drag coefficient by means of
Frictional Force
Force by Newton's second Law
Where,
m = mass
a= acceleration
Kinetic frictional coefficient
g = Gravity
Equating both equation we have that
Therefore,
Re-arrange to find x,
The distance traveled by the car depends on the coefficient of kinetic friction, acceleration due to gravity and initial velocity, therefore the three cars will stop at the same distance.
