Physics

please tell me a situation in which there is an acceleration but the velocity is zero

This discussion board is a place to discuss our Daily Challenges and the math and science related to those challenges. Explanations are more than just a solution — they should explain the steps and thinking strategies that you used to obtain the solution. Comments should further the discussion of math and science.

When posting on Brilliant:

Use the emojis to react to an explanation, whether you're congratulating a job well done , or just really confused .
Ask specific questions about the challenge or the steps in somebody's explanation. Well-posed questions can add a lot to the discussion, but posting "I don't understand!" doesn't help anyone.
Try to contribute something new to the discussion, whether it is an extension, generalization or other idea related to the challenge.
Stay on topic — we're all here to learn more about math and science, not to hear about your favorite get-rich-quick scheme or current world events.

This looks like a homework question.

Anyways, when a projectile is thrown straight up, at the highest point, acceleration is $-g$ , and velocity is $0$

at the highest pt when we throw a ball in air,there a=-g and v=0.....

Imagine you are sitting in a car whose wheels are stuck in slippery moist mud(Or on some friction less surface). Now you try to drive the car by accelerating it, but it does not move because of no friction.
