Answer:
According to the standard big bang model of cosmology, time began together with the universe in a singularity approximately 14 billion years ago.
Explanation: the big bang
Solution :
Given :
Mass of the object attached to the spring, m = 2 kg
Velocity of the object as it moves, V = 5 m/s
Amplitude of the object as it swings, A = 2.5 m
We have to find the frequency of the object.
We known,

Therefore, 

f = 0.32 Hz
Therefore the frequency of the object is 0.32 hertz when the amplitude of the 2 kg mass is 2.5 m moving a speed of 5 m/s.
Initial velocity = 5mph
final velocity = 7mph
B I think hope this helps
You use more significant figures. 5 sigfigs (1.0985) is more accurate than 2 sigfigs (1.0)
