Car Minimum

AI Thread Summary

To determine the minimum stopping distance for a car moving at 77.0 mi/h, first, calculate the acceleration using the stopping distance of 42.0 ft at 44.0 mi/h. The relevant formula that relates acceleration to velocity and time is essential for this calculation. Once the acceleration is established, apply it to find the stopping distance for the higher speed. This approach ensures accurate results based on the same rate of acceleration. Understanding these principles is crucial for solving similar physics problems effectively.

The minimum distance required to stop a car moving at 44.0 mi/h is 42.0 ft. What is the minimum stopping distance for the same car moving at 77.0 mi/h, assuming the same rate of acceleration?

how do i go about doing this problem.? pls help.

Well, you need to find out the acceleration of the first car. Do you know a formula that relates acceleration to velocity and time?

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 'I've come across another fluid pressure problem I don't understand'

Neglect gravity other than that of water; neglect friction. F1=ρgsh=1000*10*1*(1+4)=50000 N; F1=ρgsh=1000*10*0.1*4=4000 N; F3=50000-4000=46000 N?

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...
