Answer:
15 miles.
Explanation:
Displacement is the position you are in now relative to the position you were in when you started. If you had stopped at the dry cleaner's, your displacement would be 12 miles. However, you traveled back to your house and then 15 miles West of that, meaning you are now 15 miles away from your starting position.
To solve this problem it is necessary to apply the concepts related to the conservation of the Momentum describing the inelastic collision of two bodies. By definition the collision between the two bodies is given as:
Where,
= Mass of each object
= Initial Velocity of Each object
= Final Velocity
Our values are given as
Replacing we have that
Therefore the the velocity of the 3220 kg car before the collision was 0.8224m/s
Hey! I just started AP Physics 1 as well.
Lets break it down:
Displacement is the change in the position of a vector.
Net means total
This means that Net displacement means the addition of displacements. Also said as the "vector sum of the individual displacements".
This is all I know. Good luck!
