AnswersGiven, the radius of the wheel is 1m. so,its circumference is 2π m
AnswersGiven, the radius of the wheel is 1m. so,its circumference is 2π mwhen it rotates half, the initial point of contact is vertically above the final point of contact.thus,the three points form a right triangle.
AnswersGiven, the radius of the wheel is 1m. so,its circumference is 2π mwhen it rotates half, the initial point of contact is vertically above the final point of contact.thus,the three points form a right triangle.by pythagoras theorem, we solve it to get the magnitude of displacement,which is the hypotenuse.
