C. The canoe's path will be a diagonal line from northeast to southwest.
Explanation:
We can solve this problem by using vector addition rules.
In fact, we know that:
- The velocity of the canoe has a component in the south direction, due to the velocity of the river which points towards south
- The canoe itself is trying to go from the eastern shore towards the western shore --> this means that the canoe has also a component of the velocity in the west direction
This means that the resultant velocity of the canoe must be in a direction intermediate between the directions of its two components: therefore, in the southwest direction.
Therefore, this means that
C. The canoe's path will be a diagonal line from northeast to southwest.

Answer:
21 miles
Explanation:
3 miles an hour for 7 hours
Its simply 7m*3m/hr=21 miles
They both-
1) are vector fields
2) they both transmit forces between objects

Answer:
(a) Girl acceleration = 0.15 m/s², (b) Sled acceleration = 0.93 m/s²
Explanation:
Given:
M1=Mass of girl = 43 Kg
M2= mass of Sled = 7.1 Kg
Force F= 6.6 N
To Find (a) a1 = girl acceleration (b) a2 = sled acceleration
Solution:
F1 = F2 = F (Newton's 3rd Law)
F=ma (Newton's 2nd Law)
(a) F = M1a1
⇒a1 = F/M1 = 6.6 N / 43 Kg = 0.15 m/s²
(b) a2 = F / M2 = 6.6 N / 7.1 Kg = 0.93 m/s²
