Question 3 10.5 pts An object object travels 38 meters in the +x direction, and then immediately travels some distance in the-x direction. when moving in the -x direction, its average speed is 4.1 m/s. How long does the object have to travel in the-x direction such that the displacement for the entire trip is O m? Answer in seconds. Question 4 10.5 pts An object is initially traveling in the +x direction at 39 m/s. A constant acceleration of 7.3 m/s2 is applied in the -x direction. How long does it take the object to stop in seconds?

Explanation / Answer

3.

Displacement need to travel, d= 38 m

Av velocity= 4.1 m/s

Time= 38/4.1= 9.268 s

=========

4.

Using 1st equation of motion

t= 39/7.3= 5.342 s

===========

Comment in case any doubt.. good luck
