We have that for the Question ,it can be said that he spring constant k of a spring designed to bring a 1300 kg car to rest from a speed of 95 km/h so that the occupants undergo a maximum acceleration of 5.0g is
k=4449.3Nm^{-1}
From the question we are told
What should be the spring constant k of a spring designed to bring a 1300 kg car to rest from a speed of 95 km/h so that the occupants undergo a maximum acceleration of 5.0g?
Generally the equation for the angular frequency is mathematically given as

Spring constant, k = 4485.24 N/m
Explanation:
It is given that,
Mass of the car, m = 1300 kg
Speed of the car, v = 95 km/h = 26.38 m/s
Acceleration, a = 5 g
We need to find the spring constant k of the spring such that,
m a = k x
The elastic potential energy is balanced by the kinetic energy of the spring such that,
k = 4485.24 N/m
So, the spring constant of the spring is 4485.24 N/m. Hence, this is the required solution.
