A 1410-kg submarine rises straight up towards the surface. Seawater exerts both an upward buoyant force of 16760 N on the submarine, as well as a downward resistive force of 1080 N. What is the submarine's acceleration?
the upward force is 16760N while your two downward forces are 1080N and 13832.1N that comes from gravity x mass. Subtract the two then divide by the mass of the submarine
To find the submarine's acceleration, we need to apply 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.
The net force acting on the submarine can be calculated by subtracting the downward resistive force from the upward buoyant force:
Net force = Buoyant force - Resistive force
Net force = 16760 N - 1080 N
Net force = 15680 N
Now, we can apply Newton's second law to find the acceleration:
Net force = Mass * Acceleration
Acceleration = Net force / Mass
Acceleration = 15680 N / 1410 kg
Calculating the acceleration:
Acceleration = 11.1 m/s²
Therefore, the submarine's acceleration is 11.1 m/s².
