displacement and position

Question

A cyclist maintains a constant velocity of 5.5 m/s headed away from point A. At some initial time, the cyclist is 259 m from point A.

 

What will be his displacement from his starting position after 54 s

 

What will be his position from point A after that time?

Answer 1

You are given:

 

v = 5.5 m/s

d = 259 m

 

where v is velocity and d is displacement

 

Let us first find the displacement after 54 s.

 

d = vt

 

d = (5.5 m/s)(54 s)

d = 297 m

 

Lets find his position from point A after that time.

 

We take the difference between the displacement at initial time and 54 seconds.

 

297 m - 259 m = 38m

 

His position from point A after that time is 38m.
