The correct choice is
A. III and IV only
according to newton's second law, force is directly proportional to the acceleration of the object and vice versa and is given as
F = ma
where F = net force on the object
m = mass of the object
a = acceleration of the object
when an unbalanced force acts on an object, the object experiences acceleration. we know that acceleration is nothing but the time rate of change of velocity. hence object experience change in velocity. The velocity can change either by a change in speed or by change in direction of motion.

Most likely the baseball because it weighs less therefore with the same force it will go further due to the fact it weighs less it would be easier to apply force and the less it weighs there is also less force acting upon it.
Answer:
The answer would be 3
Explanation:
This is because a civic would have the greater acceleration and the impact force would be higher for the civic.
Answer: Option (1) is the correct answer.
Explanation:
Formula to calculate correlation coefficient is as follows.
Correlation coefficient = 
As the slope for given equation is positive so, it means that the correlation will also be positive in nature.
Therefore, we will calculate the value of correlation coefficient as follows.
Correlation coefficient = 
=
= 0.54
Thus, we can conclude that the correlation coefficient, r is 0.54.
