Answer:
See the explanation below
Explanation:
After the mass is pulled, you have all three types of energy; potential, kinetic and elastic. Elastic as it has extension of the spring, potential energy as the mass is one meter above the ground level, and kinetic energy as the mass is in motion.
The following are the equations for calculating the different energies.
![E_{elas}=0.5*k*x^2\\where:\\k = spring constant [N/m]\\x = distance [m]\\\\E_{pot} =m*g*h\\where:\\m = mass [kg]\\g = gravity = 9.81[m/s^2]\\h = elevation [m]\\\\E_{k}=0.5*m*v^2\\where:\\m= mass [kg]\\v = velocity [m/s]](https://tex.z-dn.net/?f=E_%7Belas%7D%3D0.5%2Ak%2Ax%5E2%5C%5Cwhere%3A%5C%5Ck%20%3D%20spring%20constant%20%5BN%2Fm%5D%5C%5Cx%20%3D%20distance%20%5Bm%5D%5C%5C%5C%5CE_%7Bpot%7D%20%3Dm%2Ag%2Ah%5C%5Cwhere%3A%5C%5Cm%20%3D%20mass%20%5Bkg%5D%5C%5Cg%20%3D%20gravity%20%3D%209.81%5Bm%2Fs%5E2%5D%5C%5Ch%20%3D%20elevation%20%5Bm%5D%5C%5C%5C%5CE_%7Bk%7D%3D0.5%2Am%2Av%5E2%5C%5Cwhere%3A%5C%5Cm%3D%20mass%20%5Bkg%5D%5C%5Cv%20%3D%20velocity%20%5Bm%2Fs%5D)

Answer:
plane LA534 will have to decrease it speed by twice that of plane LA639.
Explanation:
Since both planes want to land there must be a decrease in speed.
We are told that plane LA534 velocity is twice that of plane LA639.
Now for the two planes to land without a crash. the opposite or reverse will be the case in terms of deceleration, that is
Plane LA639 will have to decrease its speed by twice the decrease in speed of plane LA534
