How Do You Calculate Acceleration at Different Times from a Velocity-Time Graph?

AI Thread Summary
To calculate acceleration at different times from a velocity-time graph, one must analyze the segments of motion. The car maintains a constant velocity of +20 m/s for 5 seconds, then accelerates to +40 m/s over 4 seconds, followed by a deceleration to 0 m/s. At t = 3 seconds, the acceleration is zero since the car is moving at a constant velocity. At t = 11 seconds, the car is at rest, resulting in zero acceleration as well. Understanding the relationship between velocity and time is crucial for determining acceleration at specific intervals.

A car travels at a constant velocity of +20 m/s for 5 seconds, than constantly accelerates up to + 40 m/s in 4 seconds. Then the car decelerates constantly until it reaches a velocity of 0 m/s, and rests for 1 second.

What is ax at t = 11 s? And what is ax at t = 3 seconds?

I'm sure if anyone could help me with either I would learn the process and be able to do the other by myself, thank you :)

Isn't there a format for posing problems for which you need help?

Dunno, I just joined like an hour ago... chill xD

- & I figured out how to solve this :)

what do you mean with ax? acceleration times position? or is it street lingo for acceleration?

kids these days..

Thread 'Voltmeter readings for this circuit with switches'

TL;DR Summary: I would like to know the voltmeter readings on the two resistors separately in the picture in the following cases , When one of the keys is closed When both of them are opened (Knowing that the battery has negligible internal resistance) My thoughts for the first case , one of them must be 12 volt while the other is 0 The second case we'll I think both voltmeter readings should be 12 volt since they are both parallel to the battery and they involve the key within what the...

Thread 'Correct statement about a reservoir with an outlet pipe'

The answer to this question is statements (ii) and (iv) are correct. (i) This is FALSE because the speed of water in the tap is greater than speed at the water surface (ii) I don't even understand this statement. What does the "seal" part have to do with water flowing out? Won't the water still flow out through the tap until the tank is empty whether the reservoir is sealed or not? (iii) In my opinion, this statement would be correct. Increasing the gravitational potential energy of the...
