AI Thread Summary
To calculate the constant acceleration needed for an airplane to stop from a southwest velocity of 59 m/s over a distance of 1.2 km, the equation d = (v_f^2 - v_i^2) / (2a) can be utilized. Here, v_f is the final velocity (0 m/s upon stopping), and v_i is the initial velocity (59 m/s). Rearranging the equation allows for solving acceleration (a) as a = (v_i^2) / (2d). Substituting the values gives the necessary acceleration to determine how quickly the airplane must decelerate. This approach effectively addresses the problem of calculating constant acceleration during landing.

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 .
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...
