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

Answer:

The distance in -x axis is 39.77 m

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

$v=\dfrac{d}{t}$

Put the value into the formula

$v=\dfrac{24}{3.5}$

We need to calculate the velocity in -x axis

$v=\dfrac{x}{9.3-3.5}$

We need to calculate the distance

Using formula of average velocity

$\dfrac{\dfrac{24}{3.5}-\dfrac{x}{9.3-3.5}}{2}=0$

$x=\dfrac{24}{3.5}\times5.8$

$x=39.77\ m$

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