Question

An object object travels 24 meters in the +x direction for 3.5 seconds, and then immediately travels some distance in the -x direction. After a total time of 9.3 seconds, the object's average velocity is 0 m/s. What distance did the object travel in the -x direction?

Answer 1

The distance in -x axis is 39.77 m

Step-by-step explanation:

Given that,

Distance in +x axis = 24 m

Time = 3.5 sec

Total time = 9.3 sec

Average velocity = 0

We need to calculate the velocity in +x axis

`v=(d)/(t)`

Put the value into the formula

`v=(24)/(3.5)`

We need to calculate the velocity in -x axis

`v=(x)/(9.3-3.5)`

We need to calculate the distance

Using formula of average velocity

`((24)/(3.5)-(x)/(9.3-3.5))/(2)=0`

`x=(24)/(3.5)*5.8`

`x=39.77\ m`

Hence, The distance in -x axis is 39.77 m.
