Answer:
The book is titled Solid State or Condensed Matter
Explanation:
I created the illustration found in the accompanying file.
There are two images included.
The upper one illustrates the impacts of:
- scaling vector A by a factor of 1.5, depicted in red with a dashed line.
- scaling vector B by -3, shown in purple with a dashed line.
The lower image displays the resultant vector: C = 1.5A - 3B.
The approach involves relocating the tail of vector -3B to the tip of vector 1.5A while maintaining the angles.
Next, an arrow is drawn from the tail of 1.5A to the position of -3B after this shift.
The arrow representing the result is vector C, marked with a black dashed line.
Set the initial location of kitten A on the left side of the field (designated as point A) at the origin, running east which is the positive direction. Kitten B starts at position
, while kitten A’s beginning spot is
.
Kitten A moves with a velocity of
, and kitten B with
. Their positions over time are described by


The collision occurs when the positions are the same, i.e. when
. Solving this gives



Which results in approximately 6.8 seconds, considering significant figures.
Explanation:
The initial time is t₁ = 2:30 pm
The final time is t₂ = 2:30:45
We must analyze the students' motion concerning time. The final time exceeds the initial time by 45 seconds.
Change in time,

Therefore, this is the solution we need.
