1. The problem statement, all variables and given/known data
A police car stopped at a set of lights has had a speeder pass it at 100km/hr. if the police car can accelerate at 3.6m/s^2, how long does it take to catch up to the speeder

2. Relevant equations
I'm not sure what I can do with the given info

3. The attempt at a solution
Same as above

You must have been given some equations to look at? Are you using a textbook? No notes from class? This should be a plug and chug type problem.

there is nothing, it was a sheet online that my teacher gave to me.
We just started physics, and are currently on the unit of Motion in a straight line in kinematics. we were told to use any formulas we know (5 main kinematics) but im not sure where to find the remaining variable

Is it possible to link to that sheet here?

What are the kinematics equations that you know?

### ExaltedProphecy

there called the 5 main kinematics equations. its faster to search it up then putting them in this

### Greg Bernhardt

You got to work with us. Which of the equations is your best guess to use?
