Question

a glider of length 13.5 cm moves on an air track with constant acceleration. A time interval of 0.545 s elapses between the moment when its front end passes a fixed point A along the track and the moment when its backs end passes this point. Next, a time interval of 1.33 s elapses between the moment when the back end of the glider passes point A and the moment when the front end of the glider passes a second point B farther down the track. After that, an additional 0.352 s elapses until the back end of the glider passes point B.

a) Find the average speed of the glider as it passes point A?

B) find the acceleration of the glider

C) explain how you can compute the acceleration without knowing the distance between points A and B

A glider of length 12.5 cm moves on an air track with constant acceleration. A time interval cr 0.54 s elapses between the moment when its front end passes a fixed point along the track and the moment when its back end passes this point. Next, a time interval of 1.33 s peas batw the moment when tho back and of th glidor passes Point and the moment han the front and of the glider passes a soennd point farther down the track. Aftar that, an additional o.352 s elapses until tha back nd of th glider passes puint (a) Find th ye speed of the glid as it pazzes point O. cm/s2

Explanation / Answer

a) Average speed = total distance / total time = 0.135 / 0.545 = 0.2477 m/s

It is avg speed of glider as it passes the point A

b) Acceleration a= v/t = 0.2477 / 0.545 = 0.454 m/s2

c) By the definition of acceleration a = v/t
