a.
To calculation:
Resultant velocity of Camilla.
a.
Answer to Problem 27PPS
Resultant velocity of Camilla is
Explanation of Solution
Given information:
Camilla is running at
Speed of wind from behind
Calculation:
Initially find component form of wind vector.
The wind vector is
Since Camilla is running in a straight line her
The Camilla’s vector is
Add the winds vector with the Camilla’s vector.
Now use Pythagoras theorem to find the resulting velocity.
Hence, Resultant velocity of Camilla is
b.
To calculation:
Time that Camilla will take to complete the dash.
b.
Answer to Problem 27PPS
Time that Camilla will take to complete the dash is
Explanation of Solution
Given information:
Camilla is running at
Speed of wind from behind
Calculation:
Initially find component form of wind vector.
The wind vector is
Since Camilla is running in a straight line her
The Camilla’s vector is
Add the winds vector with the Camilla’s vector.
Now use Pythagoras theorem to find the resulting velocity.
Now, use dimensional analysis for finding out the time hat Camilla will take,
Hence, Time that Camilla will take to complete the dash is
