Answer:
Then the difference of weight between the two cars are:
Δw = 14210 - 5292 = 8918 N
Explanation:
An object's weigh due to the gravitational attraction force of the earth is:
w = mg
Where: m is the object's mass
g is the gravitational acceleration in the surface earth
g = 9.8 m/s2
The the ultralight car's weight is:
And the Honda Accord's weight is:
Then the difference of weight between the two cars are:
Δw = 14210 - 5292 = 8918 N
Answer:
Average speed: approximately .
Average velocity: approximately (to the north.)
Explanation:
Consider an object that travelled along a certain path. Distance travelled would be equal to the length of the entire path.
In contrast, the magnitude of displacement is equal to distance between where the object started and where it stopped.
In this question, the path George took required him to travel in total. Hence, the distance George travelled would be
. However, since George stopped at a point
to the north of where he started, his displacement would be only
to the north.
Divide total distance by total time to find the average speed.
Divide total displacement by total time to find average velocity.
The total time of travel in this question is .. Therefore:
.
