Answer:
12 m/s
Explanation:
divide distance over time
72/6 = 12
In #8, the distance and the (magnitude of displacement) are equal, because he crawled in a straight line.
Displacement = (straight-line distance from start-point to end-point) in the direction from start to end, regardless of what route was actually followed.
Displacement = 5m, in the negative direction.
In #9 . . . distance will be the same. Displacement is going to be the same magnitude, but in the positive direction.
This is so simple that it's hard to talk about.
In #8, "What was the bug's distance ?". "Distance was 5 meters.". "What was the bug's displacement ?", "Displacement was 5 meters backwards."
In #9, What was the bug's distance ?". "Distance was 5 meters.". "What was the bug's displacement ?", "Displacement was 5 meters forward."
Explanation:
We have,
Initial speed of a softball is 3.89 m/s
Deceleration of the ball is -1.44 m/s²
Distance covered by the ball is 4.8 m
It is required to find the time that the ball take when it slides. Let t is time. Using second equation of motion :
Putting all the values we get :
