Answer:
(B)1005 feet
Step-by-step explanation:
In the attached diagram
|AG|=1400 feet
Distance from point C to point G=|CG|
Using Trigonometry in Triangle ACG
Using Trigonometry in Triangle BCG'
Therefore, the distance from balloon B from balloon A
=CG+CG'
=808+197
=1005 feet
Answer:
a) distance halfway = 16.49 [m], displacement halfway = 10.5 [m]
b) distrance traveled increases when the child completes one circuit of the track.
Step-by-step explanation:
a) Distance is a scalar quantity that tells you how much space a body has covered when moving. Displacement is a vector quantity that tells you how far from its initial position and object is after moving.
In this case, the child goes around the track only halfway from point 1 to point 2. We know the circunference or perimeter of a circle to be 2*PI*radius. We also know the child only when halfway, so we need to divide the perimeter by 2, thus we get distance = PI*radius
And now that we know the definition of displacement, we can easily see that the child went from point 1 to point 2 which is located at a distance of 1 diameter from point 1:
b)What happens to the distance when the child completes one circuit? The distance will increase beause he is now completing the circuit so he is covering more ground in his movement:
32.99 is more than 16.49 so we are certain that the distance increases.
