When a rock thrown straight up reaches the exact top of its path, its velocity is?
Understand the Problem
The question is asking about the physics principles related to a rock thrown vertically upwards. Specifically, it inquires about the velocity and acceleration of the rock at the peak of its trajectory.
Answer
zero and its acceleration is 10 m/s².
The final answer is zero and its acceleration is 10 m/s².
Answer for screen readers
The final answer is zero and its acceleration is 10 m/s².
More Information
When a rock is thrown upwards, it slows down due to gravity until it reaches the top, where its velocity is zero. However, gravity still acts on it, resulting in an acceleration of about 9.8 m/s² downward.
Tips
A common mistake is thinking the acceleration is zero at the top. However, gravity continuously acts on the rock.
