To solve this problem it is necessary to apply the concepts related to the conservation of the Momentum describing the inelastic collision of two bodies. By definition the collision between the two bodies is given as:

Where,
 = Mass of each object
= Mass of each object
 = Initial Velocity of Each object
= Initial Velocity of Each object 
 = Final Velocity
= Final Velocity
Our values are given as




Replacing we have that 



Therefore the the velocity of the 3220 kg car before the collision was 0.8224m/s

Answer: 1. The field energy will increase 
2. The energy increases, and the lines of force are denser
3. It points toward the field of earths magnetic poles
4. 1 and 2 only
5. 2, 4, 1, 3
Explanation: just took it
 
        
             
        
        
        
Answer:
We know that Force = mass × acceleration 
By substituting the values we get, 
30 N = 15 kg × a (where a is acceleration)
Or we can write it as 
15 kg × a = 30 N
Transposing 15 to RHS,
a = 30 ÷ 15 m/s²
Therefore, acceleration = 2 m/s²
