- A car traveling 85 km/h slows down at a constant 0.50 m/s` just by "letting up on the gas: Calculate (a) the distance the car coasts before it stops. (h) the time it takes to stop. and (c) the distance it travels during the first and fifth seconds. .
The wording is so difficult to figure out, honestly. Physics has always been a struggle for me because wordings like "the distance it travels during the first and fifth seconds" confuses me. Idk maybe it's just a me problem, heh. Thank you for this video! Helped a lot.
But for me I'm still lost first and fifth second, were he got time so I was thinking that in first second as t we put 1s in fifths second as t we put 50s
Yes, explanation is cool now were I've lost question (c) distance it travels first and fifth
Where did you get 4s and 5s as Time were there is no time in question🙏
May be a little late lmao, but they are asking for the 5 second interval. So the first second would be 0-1, the second second would be 1-2, etc. Thats why the fifth second is from 4-5. It goes by intervals
The wording on the last question makes it sound like they want to know how far it traveled in 5 seconds 😭
How 85km/h will be a initial velocity
so how long before it stops? im lost after converting
what happened to the -.5? I have a problem like this but the a is -6. Do I have to disregard it too?
This was very helpful!
Thank you so much! Keep it up mate! :)
Thanks! glad I could help!
@@TheAnswerKey I've got an idea, what if you focus on making a playlist/series that focuses on each section of AP Physics (I.E a Kinematics playlist, a Dynamics playlist, etc.). Just an idea because you teach it well :)
@@PolyStylized Thanks for the kind words. I do plan on going through physics 1 and making videos on each topic. I will probably finish all of the videos on physics 1 by the end of the year.
TheCheatSheet you’re a legend! I can’t wait to see the future videos :)
But 85 km/h is equal to 12.5 m/s
How to calculate distance after 't' second if acceleration is given
Do you want me to explain to you how to do that in general? or are you confused about some part of the video?
@@TheAnswerKey yes
Yes u wanted to explain
@@vloggermedia5539 It depends on what variables you are given along with acceleration. What you do is take the variables you are given, and then plug them into an equation with delta x, which is what you are trying to find. So you just plug in the time and acceleration given and the initial velocity and that will allow you to solve for the distance traveled.
What is the initial velocity?
