A 1450-kg submarine rises straight up towards the surface. Seawater exerts both an upward buoyant force of 16890 N on the submarine, as well as a downward resistive force of 1010 N. What is the submarine's acceleration?

mass= 1450 kg

buoyant force = 16890 N
resistive force = 1010 N

Force= F(buoyant) - F(resistive) - mg
F= 16890-1010 - (1450 x 9.8)
F= 1670 N

F= ma
1670= (1450)a
Solve for acceleration

Well, let's see. The submarine experiences an upward buoyant force of 16890 N and a downward resistive force of 1010 N. To calculate the submarine's acceleration, we need to take into account these two opposing forces.

So, we have the net force acting on the submarine, which can be calculated by subtracting the resistive force from the buoyant force:

Net force = 16890 N - 1010 N

Now, we can use Newton's second law of motion, which states that force is equal to mass multiplied by acceleration:

Net force = mass × acceleration

Plugging in the values, we get:

16890 N - 1010 N = 1450 kg × acceleration

Simplifying the equation:

15880 N = 1450 kg × acceleration

And solving for acceleration:

acceleration = 15880 N / 1450 kg

After doing the math (which I'll leave to you), you should end up with the value for the acceleration. Just remember, I'm not a calculator, I'm just here to make you smile!

To find the submarine's acceleration, we need to use Newton's second law of motion, which states that the net force acting on an object is equal to the mass of the object multiplied by its acceleration.

First, let's consider the forces acting on the submarine:
- The upward buoyant force exerted by the seawater, which is equal to 16890 N.
- The downward resistive force exerted by the seawater, which is equal to 1010 N.

Since the submarine is rising straight up, the net force acting on it will be the difference between the upward buoyant force and the downward resistive force.

Net Force = Buoyant Force - Resistive Force
Net Force = 16890 N - 1010 N
Net Force = 15880 N

Now we can calculate the submarine's acceleration using Newton's second law:

Net Force = Mass x Acceleration

Rearranging the formula, we can calculate the acceleration:

Acceleration = Net Force / Mass
Acceleration = 15880 N / 1450 kg
Acceleration ≈ 10.966 m/s²

Therefore, the submarine's acceleration is approximately 10.966 m/s².

To find the submarine's acceleration, we need to use Newton's second law of motion, which states that the force acting on an object is equal to the mass of the object times its acceleration: F = ma.

In this case, we have two forces acting on the submarine: the upward buoyant force and the downward resistive force. The buoyant force is directed upwards and has a magnitude of 16890 N, while the resistive force is directed downwards and has a magnitude of 1010 N.

To find the net force acting on the submarine, we need to subtract the resistive force from the buoyant force:

Net force = Buoyant force - Resistive force
= 16890 N - 1010 N
= 15880 N

Now we can use Newton's second law to find the acceleration:

15880 N = 1450 kg x a

To solve for acceleration (a), we divide both sides of the equation by the mass of the submarine:

a = 15880 N / 1450 kg
= 10.97 m/s²

Therefore, the submarine's acceleration is approximately 10.97 m/s².

a = f / m = (16890 - 1010) / 1450
