The answer is 20-3x=-7 explanation
A = (-3)
B = (0.5)
|AB| = |0.5 - (-3)| = |0.5 + 3| = |3.5| = 3.5
The air resistance acting on the un-crumbled sheet is greater.
The answer to your question is D
We are given displacement = 20 meters.
Time given = 4.7 seconds.
Velocity = 4.3 m/s.
Please note : Velocity is a vector quantity. A vector quantity depends on magnitude and direction as well.
We are given magnitude of displacement = 20 meter and time 4.7 seconds but the direction is missing there.
If it would be in forward direction it would be positive and if it would be in backward direction, it would be of negative.
Therefore, <u>"B)the direction"</u> is correct option.
