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.
Explanation:
It is given that,
Initial speed of the broad jump, u = 12 m/s
It is launched at an angle of 20 degrees above the horizontal. Let t is the time for which the track star i in the air before returning to Earth. The motion of the track star in the broad jump can be treat as the projectile motion. The time of flight of the projectile is given by :
Putting all the values in above equation as :
t = 0.837 seconds
So, the time for which the track star is in air is 0.837 seconds. Hence, this is the required solution.
