While john is traveling along a straight inter-
state highway, he notices that the mile marker
/reads 256 km. john travels until he reaches
the 138 km marker and then retraces his path
to the 173 km marker.
what is john's resultant displacement from
the 256 km marker?
answer in units of km.

83km

Explanation:

Distance from the 256km marker to 138km markeris (256 - 138) = 118km

Then when he traces back to the 173km markerhe moves (173 - 138) = 35km but its in the opposite direction...so hence..its -35km(since when calculating displacement...direction has to be accounted for)...

Total displacement from the 256km marker

; 118 + (-35) = 83km

well, you would divide 135 by 33 to get your answer. then that is how many seconds it would take. boardman should fly about 132 m or 4.090909090909091 seconds.

jupiter is the largest planet in our solar system, having a mass and radius that are respectively, 318 and 11.2 times that of earth. suppose that an object falls from rest near the surface of each planet and that the acceleration due to gravity remains constant during the fall. each object falls the same distance before striking the ground. determine the ratio of the time of fall on jupiter to that on earth.
