hmm so if we want to find the linear acceleration,we can apply kinematics equation solve for it? But however,can we treat the circle as a straight line??Arent we suppose to take our position with respect to the cirlce?hence the displacement equals to zero?? is there any other way than using...

ok i think i need to revist this question.let say its a circular motion with both linear accleleration and a radial acceleration,and the object starts from rest,i'm told to find the angle made by the total acceleration with the radial acceleration after the object completes one round of...

hmm,why the torque from the pressure is equal to the intergral of pressure wrt to r? in my tutor solution,he intergrate pressure wrt to area,and the right hand side he intergrate wrt to both the angle and the term r.Thats a double intergral at the right hand side.

ok the question goes sth like this,an equation of p=c1+c2*r^0.625cos@,where p is the pressure exerted on the soil,c1 & c2 are constant to be determined,r& @ are polar coordinates.(@ measured fr the x-axis which is of direction south) now the question states that pisa lean at an angle of...

cool i needed a proof like this,thx guys.well what set me pondering me was that my friends said if u could imagine the circle as a string,and now you take it and separate and extend into a straight line,you will get displacement.This of course doesn't make sense.In addition, one of them pointed...

erm just want to clarify this.If one were to move in a circular motion,and u complete one revolution thus meaning you come back to the same point to where you started off,is your displacement equals to zero??

the charges will move until the pd across them is the same.

during a circular motion,the speed may be constant,but the velocity is constantly changing.the vector sum of the velocity points towards the center hence the acceleration is also towars the center.hope that helps.
