Answer:
57.0 m
Explanation:
Given:
v₀ = 0 m/s
t = 3.41 s
a = 9.8 m/s²
Find: Δx
Δx = v₀ t + ½ at²
Δx = (0 m/s) (3.41 s) + ½ (9.8 m/s²) (3.41 s)²
Δx = 57.0 m
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

Answer:
7.01yard/sec
Explanation:
Given parameters:
Initial position = 50yard
Final position = 12yard
Time = 5.42s
Unknown:
Average speed of runner = ?
Solution:
To solve this problem;
Speed = 
Distance covered = Initial position - final position = 50 - 12 = 38yards
So;
Speed = 
= 7.01yard/sec
