How much time does it take to change your displacement by 25.0m east?

AI Thread Summary
To determine the time required to change displacement by 25.0 m east while walking at a constant speed of 1.65 m/s at an angle of 16.2° north of east, the correct approach involves using the equation vx = (v0 cosθ)t. This equation calculates the eastward component of velocity. By substituting the values into the equation, the time can be easily calculated. The discussion confirms the use of this equation for finding the time. Understanding the components of velocity is crucial for solving displacement problems.

As you walk to class with a constant speed of 1.65 m/s , you are moving in a direction that is 16.2° north of east.

How much time does it take to change your displacement by 25.0 m east?

I know that v0 = 1.65 m/s. Would I use the equation: x = (v0 cosθ)t?Any help or advice would be much appreciated.

Maybe you meant to say vx = (v0 cosθ)t

Yes. Would that be correct equation to use?
 
Yes, to get the velocity in the x (eastward) direction. Using this result, you can easily determine t.

Thank you.
 
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 .
