The problem involves a police car attempting to catch a speeder traveling at 100 km/hr, with the police car having an acceleration of 3.6 m/s². The context is within the subject area of kinematics, specifically focusing on motion in a straight line.
The discussion has seen participants questioning the available information and resources. Some have offered to help clarify the kinematic equations, while one participant has indicated they figured out a solution by substituting formulas and creating a quadratic equation.
Participants mention that they are new to physics and are currently learning about kinematics. There is a reference to a worksheet provided by the teacher, but some express difficulty in finding the necessary variables to apply the equations.
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.ExaltedProphecy said:I'm not sure what I can do with the given info
Is it possible to link to that sheet here?ExaltedProphecy said:there is nothing, it was a sheet online that my teacher gave to me.
What are the kinematics equations that you know?ExaltedProphecy said: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 I am not sure where to find the remaining variable
You got to work with us. Which of the equations is your best guess to use?ExaltedProphecy said:there called the 5 main kinematics equations. its faster to search it up then putting them in this
Some other readers may be interested how you figured it out?ExaltedProphecy said:its ok, i figured it out, thanks
I put the information from the cop into 2 separate formulas. Then I substituted 1 formula into the other, creating a quadratic. I then used the quadratic formula, keeping the positive amount as my final answerGreg Bernhardt said:Some other readers may be interested how you figured it out?
