For this case we can write each one of the vectors in the following way:
This means that the x-axis is defined as positive towards the west.
Then, the resulting vector is:
Answer:
Displacement vectors of 10 m west and 14 m west make a resultant vector that is 24 m west
Answer:
Option A
The first route will be shorter
Explanation:
Considering the motion when the airline heads westward, the north direction speed is given by
Distance to destination is 1500 Km= 1500000 m
Time for travelling=1500000/257=5836.58 seconds
Time in minutes=5836.58/60=97.3 minutes
In case the wind sends pilot off the course
Time to travel from A to point E before heading to Duluth=1500000/260=5769.23 seconds
Time in minutes=5769.23/60=96.2 minutes
Time to travel from Westward to Duluth=Distance/speed
Distance between Westward and Duluth=40*5769.23=230769.23 m
Time to travel from Westward point to Duluth=23769.23/(260-40)=1048.95 seconds
Time in minutes=1048.95/60=17.5 minutes
Total time taken when pilot changes course=96.2+17.5=113.7 minutes
Time difference=113.7-97.3=16.4 minutes
Therefore, the first route will be shorter .
Answer:
a
Her mass is
b
The measurement of the astronaut acceleration would be defined by relation
Hence it is affected by the mass of the vehicle, the acceleration of the vehicle and her mass
Now to avoid recoil on the vehicle the force on the astronaut should not be provided by the vehicle
Explanation:
From the question we are told that
The net external force is
The astronaut's acceleration
Generally force is mathematically represented as
Where m is the mass of the astronaut
Now making m the subject in order to obtain the mass we have
Now when this force is applied it is both felt by the astronaut and the vehicle
Hence
=>
This means that the measurement of the astronaut acceleration would be defined by relation
