A jogger runs 224 meters eastward, then 156 meters westward, then 84 meters eastward, and finally 248 meters westward.

What is the distance, magnitude and the direction of the displacement?

Explanation:

Distance is the length of the path traveled.  Displacement is the difference between the final position and initial position.

Distance = 224 m + 156 m + 84 m + 248 m = 712 m

Displacement = 224 m − 156 m + 84 m − 248 m = -96 m

Displacement = 96 m westward

what is the instantaneous acceleration of

the particle at point b?

0 meters/second?

10 meters/second?

12 meters/second?

velocity imetersisecond

15 meters/second?

20

time (seconds)

answer: 0 meters/second^2

we need to know the time interval during which the force acts. impulse of force = momentum change
