Person Chasing An Accelerating Car
A car starts from rest with constant acceleration 1 m/s^2 while a person 60 m behind runs at constant speed v0 trying to get within 20 m long enough to shout a warning. The animation tracks both the person catching up to a marker point 20 m behind the car and the point catching up to the person, paired with a v-t graph showing where velocities match. Useful for students learning relative motion, minimum distance conditions, and reading kinematics graphs.

The prompt that made it
汽车以 1 m/s2的加速度启动，同时车后 60 m 远处有一人以一定的速度 v0匀速追赶要车停下.已知在人离车的距离小于 20 m、持续时间为 2 s 喊停车才能把信息传给司机。在车后20米挂一个点，生成人追车超过点以及点追人的动态图以及v-t图像
Make the next one in this series
- Show how changing v0 changes whether the person ever gets within 20 m of the car
- Animate the position-time graphs for the car, person, and marker point together
- Extend the scenario to find the minimum v0 needed to shout for a full 2 seconds
