AI Thread Summary
The position of a particle moving along the x-axis is described by the equation x = 4.7t² - 3.2t³. To find the position when the particle reaches its maximum speed in the positive x-direction, one must first determine the velocity by differentiating the position function with respect to time. Setting the velocity equation to zero helps identify critical points, which can then be analyzed to find the maximum speed. The maximum speed occurs when the velocity changes from positive to negative. Ultimately, solving these equations yields the specific position of the particle at maximum speed.

Homework Statement



The position of a particle moving along the x-axis is given by x = 4.7t2 − 3.2t3,where x is in meters and t is in seconds. What is the position of the particle when it achieves its maximum speed in the positive x-direction?

You should try to attempt the problem along with the question!
I cannot help you unless you try to do it.
 
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...
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 .
