Answer:
The acceleration is ![a =2\ m/s^2](https://tex.z-dn.net/?f=a%20%3D2%5C%20%20m%2Fs%5E2)
Explanation:
From the question we are told that
The mass of the jumbo jet is ![m_j = 100000\ kg](https://tex.z-dn.net/?f=m_j%20%20%3D%20%20100000%5C%20kg)
The thrust is ![F_k = 50000 \ N](https://tex.z-dn.net/?f=F_k%20%3D%20%2050000%20%5C%20N)
Generally given that the jet has four engines the total thrust is
![F_t = 4 * F_k](https://tex.z-dn.net/?f=F_t%20%3D%20%204%20%2A%20F_k)
substituting values
![F_t = 4 * 50000](https://tex.z-dn.net/?f=F_t%20%20%3D%20%204%20%2A%2050000)
![F_t = 200000 \ N](https://tex.z-dn.net/?f=F_t%20%20%3D%20%20200000%20%5C%20N)
Generally the acceleration of the is mathematically represented as
![a = \frac{F_t}{m}](https://tex.z-dn.net/?f=a%20%3D%20%5Cfrac%7BF_t%7D%7Bm%7D)
substituting values
![a =2 \frac{N}{kg}](https://tex.z-dn.net/?f=a%20%3D2%20%5Cfrac%7BN%7D%7Bkg%7D)
Now
![N = kg \cdot m/s^2](https://tex.z-dn.net/?f=N%20%20%3D%20%20kg%20%20%5Ccdot%20m%2Fs%5E2)
Hence
![a =2 \frac{kg * \cdot m/s^2}{kg}](https://tex.z-dn.net/?f=a%20%3D2%20%5Cfrac%7Bkg%20%2A%20%5Ccdot%20m%2Fs%5E2%7D%7Bkg%7D)
![a =2\ m/s^2](https://tex.z-dn.net/?f=a%20%3D2%5C%20%20m%2Fs%5E2)
The relative velocity of the athlete relative to the ground is 5.2 m/s
The given parameters;
constant velocity of the athlete, V = 5.2 m/s
let the velocity of the ground = Vg = 0
The relative velocity concept helps us to determine the velocity of a moving object relative to a stationary observer.
The athlete is the moving object in this question while the ground is stationary.
The relative velocity of the athlete relative to the ground is calculated as follows;
![V/V_g = V - V_g = 5.2 - 0 = 5.2 \ m/s](https://tex.z-dn.net/?f=V%2FV_g%20%3D%20V%20-%20V_g%20%20%3D%205.2%20-%200%20%3D%205.2%20%20%5C%20m%2Fs)
Thus, the relative velocity of the athlete relative to the ground is 5.2 m/s

Spring potential energy:
E = 0.5 * k * x²
k spring constant
x spring compression
x = √(2 * E / k) = 0.7
Answer:
Ohm's law states that the current through a conductor between two points is directly proportional to the voltage across the two points.
