Final answer:
The correct answer is option C, which is 'both of the above'. Both a person standing up from a seated position and a car accelerating while driving are examples of acceleration.
Step-by-step explanation:
The correct answer is option C, both of the above. This question is in reference to phenomena that involve a change in motion.
When a person stands up from a seated position, they are changing their state from rest to motion, which is an example of an object initiating movement. Similarly, a car accelerating while driving is also changing its motion; it is increasing its speed, which constitutes a change in velocity.
Both scenarios describe a form of acceleration, which in physics, is defined as a change in the velocity of an object over time. Therefore, both examples correctly depict situations where acceleration is taking place.
Acceleration is the rate of change of velocity with respect to time. When a person stands up from a seated position, they experience acceleration because they change their velocity from zero to a positive value. Similarly, when a car accelerates while driving, it experiences acceleration as its velocity increases.
Therefore, both a person standing up from a seated position and a car accelerating while driving are examples of acceleration, making option c the correct answer.
