Astudent slides a book across a desk, with a velocity of +8 m/s. when her friend catches the book, it has a velocity of +7.4 m/s. if the acceleration was a constant -5.6 m/s2, how wide is the desk? a. 0.05 m b. 0.60 m c. 0.83 m d. 1.65 m

Because acceleration was constant throughout the slide, we can show the slide lasted

Also because accleration was constant, we know the average velocity of the book was

Average velocity is also given by

so the width of the desk must have been

which means C is the most likely answer.

the answer would be 32*f

as we probably am aware that our atmosphere or air have various levels, each level has different gasses, and each gas has another porousness. at the point when the light originates from lower porousness to higher penetrability, it alters its course. with the goal that implies that when the light originates from the moon to the earth, it alters it's course a lot more occasions. it essentially implies that the state of the light piece of the moon is changed on the earth.

not copied too! hope this !
