B. Nancy is the tallest person in the class.
Answer:
F=507.7N
Explanation:
According to Newton's second law:

in this case, the football players need to drag the coach at a constant velocity, thus means with no acceleration, so:

there are 20 degrees between the two ropes that means each player exerts a force 10 degrees from the zero reference.

Answer:
true
Explanation:
common sense i am just guessing.
Answer:
The boat will move in the direction of the force exerted.
Explanation:
To describe the motion of the boat, we shall first obtain the net force acting on the boat. This can be obtained as illustrated below:
From the question given above, the following data were obtained:
Force exerted (Fₑ) = 300 N
Resistive force (Fᵣ) = 250 N
Net force (Fₙ) =?
Fₙ = Fₑ – Fᵣ
Fₙ = 300 – 250
Fₙ = 50 N
Thus, the net force acting on the boat is 50 N in the direction of the force exerted.
Since the net force is in the direction of the force exerted, the boat will move in the direction of the force exerted..!
