Answer:
In the shooting scene, you'd be able to collect the shell of the bullet and that would be one step to find out what type of gun the perpetrator used. You could go through nearby stores and look through their CCTV camera and find out what kind of car it was and maybe even catch a glimpse of the perpetrators face. However if the shooting was in a residential area you could go door to door looking for witnesses. To see if anybody heard or saw anything.
Answer:The correct answer is C
Explanation:
Answer:
Force = 400 Newton
Explanation:
Given the following data;
Mass = 100 kg
Acceleration = 4m/s²
Newton's Second Law of Motion states that the acceleration of a physical object is directly proportional to the net force acting on the physical object and inversely proportional to its mass.
Mathematically, it is given by the formula;

Hence, to find the force needed, we would use the above formula.
Substituting into the formula, we have;
Force = 100 * 4
Force = 400 Newton
