Answer:
Explanation:
v = Final velocity
u = Initial velocity
a = Acceleration
t = Time
s = Displacement
Here the kinematic equations of motion are used
Time the car is at constant velocity is 39 s
Time the car is decelerating is 5 s
Total time the car is in motion is 
Distance traveled
The total displacement of the car is 
Average velocity is given by
The average velocity of the car is .
As density = mass/volume
So
Mass = density *volume
Mass = 25,365.4 * 2.7 = 68,486.58 g

The period is 2 seconds.
A period is a time taken to make one simple harmonic motion. It can be described as time divided by how many waves do. We can write the period formula as
T = t / n
where T is period, t is time and n is the amount of simple harmonic motions.
From the question above, we know that the mass travel up and down, it means that the cycle is one simple harmonic motion.
n = 1
t = 2s
Hence
T = t / n
T = 2 / 1
T = 2 second
