Question
you go for a ride on it along the path by the Charles River. At all times, your wheels roll without slipping. At a particular instant, you are traveling in a straight line with a speed of v.(a) At that instant, the point at the very top of the front wheel has a speed of v multiplied by
.
(b) At that instant, a point on the outer edge of the front wheel, which is at the same vertical level as the center of the wheel, has a speed of v multiplied by
.
(c) At that instant, the point at the very bottom of the front wheel has a speed of v multiplied by
.
(d) Briefly justify your answer to part (c). This part won't be graded, but we ask these kinds of questions on the tests so they're good practice.
Explanation / Answer
a. 2 b. 1 c. 0 d. it is zero , in order to avoid slipping. Thus, the relative velocity of wheel from ground should be zero , or, the velocity of that point = 0. :) plzz rate !!!
