Finding Distance Traveled of Car with Constant Acceleration/Deceleration

AI Thread Summary
A car accelerates from rest at 1.8 m/s² for 10 seconds, travels at constant speed for 12 seconds, and then decelerates at 1.9 m/s² until it stops. The user initially calculated the total distance as 283.34 meters but is unsure of the steps taken to reach this conclusion. Forum participants request clarification on the calculations and relevant equations used to verify the solution. Providing detailed work is essential for identifying any errors in the approach. Accurate distance calculation involves analyzing each phase of motion separately.

Homework Statement


A car starting from rest moves with a constant acceleration of 1.8 m/s2 for 10 s, then travels with a constant speed for another 12 s, then finally slows to a stop with a constant deceleration of 1.9 m/s2. How far does it travel?

Homework Equations





The Attempt at a Solution


I tried this and got 283.34 m. I have nooo clue where to start with this. HELP!

Please show your work so we can see what you did. This is the only way we can point out errors.
 


How did you get 283.34m? What relevant equations are you using?
 

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...

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 .
