Mr. Richard's science class is conducting a variety of experiments with projectiles and falling objects. Two groups of students
2 answers:
Answer:
1. Group C; 2. Group B; 3. Group D; 4. Group A
Detailed explanation:
All equations presented fit the form
, where v₀ represents initial velocity and h₀ indicates initial height.
The first equation shows no value for v₀ and has h₀ equal to 19, demonstrating that there is no initial velocity, meaning the ball is simply dropped from a height of 19 meters—therefore, it's categorized in group C.
The second equation displays an initial velocity of 50 with no initial height, identifying it as group B.
For the third equation, it has no initial velocity but an initial height of 50, confirming its classification in group D.
Lastly, the fourth equation indicates an initial velocity of 19 and no height, placing it in group A.
