When three people with a total mass of 2.00 x 102 kg step into their 1.200 x 103 kg car, the car’s springs are compressed by 3.0 cm.

1.2.a. What is the spring constant of the car’s springs assuming they act as a single spring?
1.2.b. How far will the car lower if loaded with 3.00 x 102 kg rather than 2.00 x 102 kg

a

b

Explanation:

From the question we are told that

    The total mass of  three people is  

     The mass of the car is  

     The compression of the car spring is  

Generally the spring constant is mathematically represented as

Here F is the force exerted by the mass of three people and that of the car , this is mathematically represented as        

=>      

=>      

=>      

So

=>    

Generally if the mass which the car is loaded with is  

Then the force experienced by the spring is  

         =>      

         =>      

         =>      

Generally from the above formula the compression is  

=>    

=>          

none, its a machine

i don't understand is there any other way you can rephrase it plz let me know in the comments and i will do it.
