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 'Rolling without slipping on a curved surface'

Kindly see the attached pdf. My attempt to solve it, is in it. I'm wondering if my solution is right. My idea is this: At any point of time, the ball may be assumed to be at an incline which is at an angle of θ(kindly see both the pics in the pdf file). The value of θ will continuously change and so will the value of friction. I'm not able to figure out, why my solution is wrong, if it is wrong .

Thread 'Struggling to understand the concept of this question (ice cube in water optics question)'

TL;DR Summary: I came across this question from a Sri Lankan A-level textbook. Question - An ice cube with a length of 10 cm is immersed in water at 0 °C. An observer observes the ice cube from the water, and it seems to be 7.75 cm long. If the refractive index of water is 4/3, find the height of the ice cube immersed in the water. I could not understand how the apparent height of the ice cube in the water depends on the height of the ice cube immersed in the water. Does anyone have an...
