Well if it was traveling for an hour then the answer is 8 miles.
This is a sneaky trick question, to help you discover whether you know
one of the differences between velocity and speed.
=======================================
If you make a list of the distances and directions, and ignore the times,
you find these:
4 - west, (3 + 1) - east . . . . . zero in the east/west direction
1.5 - north, 1.5 - south . . . . . zero in the north/south direction
This jogger went out, had a nice jog around the neighborhood,and ended up exactly where he started.
Average velocity = (distance between start point and end point) / (time)
IF the question asked for average SPEED, then you would need the total distance, and divide it by the total time. But it asks for VELOCITY, and <u>that</u> only involves the straight distance between the start point and the end point, regardless of the route taken in between.
The jogger ended up exactly where he started. The distance between start and end points was zero. Average velocity is (zero) / (time) . And that fraction is going to be <em><u>Zero</u></em>, no matter how long or how short the trip was, and no matter how much time it took.
I believe the answer would be 4.5. because it wouldnt be c or d. and 2 seems too small.
Answer:
<em>The minimum pressure car tire pressure is 300,000 Pa</em>
Explanation:
<u>Pressure</u>
It's a measure of the force exerted by an object per unit surface:

Where F is the force applied on a surface area A.
We are given the total weight of a car with passengers as Ft=30,000 N and we also know the area of contact of each tire with the ground as
.
The minimum pressure each tire can have is when the total weight is evenly distributed in all four tires, thus F=Ft/4=7,500 N.
Calculating the pressure:

P=300,000 Pa
The minimum pressure car tire pressure is 300,000 Pa
<span>The change in the kinetic energy of the object as the speed changes is proportional to the square of the factor by which the speed changes. For example if the speed of the object becomes double, its kinetic energy changes to four times the initialkinetic energy. Please put brainliest ! :D
