Net acceleration = gsin(theta) = 9.8sin10 = 0.98m/s/s

Homework Statement

I am having some trouble finding out exactly how I could find net acceleration.
I know how to use it for finding force of drag, and other formulas, but for a project I need to actually find the net acceleration of me throwing a baseball.
This is a sample problem, that I need to know how to solve, and I'll use the 'method' to solve for my actual project:

Angle from horizontal (theta): 10degrees
Force of throw: 300N
Mass of ball: 2kg

Homework Equations

Fdrag = bv
Net acceleration = gsin(theta)
Sum of all forces = mg-ma

The Attempt at a Solution

I know how to find the force of drag, which is ultimately what I need...
(assuming I actually know net accleration is 5m/s/s)
Fdrag = 4.8N

But I want to know how to find net acceleration.

I know that the sum of all forces = mg-ma, but I'm not sure what to do with it. Any help is appreciated!

I can provide you with a response to your question. First, let's define net acceleration. Net acceleration is the overall acceleration of an object, taking into account all the forces acting on it. In this case, we can use the equation: net acceleration = sum of all forces / mass of the object. So for your problem, we can calculate the net acceleration by first finding the sum of all forces acting on the ball.

Using the given information, we can calculate the force of gravity (mg) acting on the ball:
Fgravity = (mass of ball) x (acceleration due to gravity)
Fgravity = (2kg) x (9.8m/s^2) = 19.6N

Next, we can calculate the force of the throw (300N) and the force of drag (4.8N) separately.

Finally, we can calculate the net acceleration by plugging in these values into our equation:
Net acceleration = (sum of all forces) / (mass of ball)
Net acceleration = (300N + 4.8N - 19.6N) / 2kg
Net acceleration = 142.2N / 2kg = 71.1m/s^2

So, the net acceleration of the ball when thrown at an angle of 10 degrees with a force of 300N is 71.1m/s^2. Keep in mind that this is the overall acceleration of the ball, taking into account the force of gravity, the force of the throw, and the force of drag.

I hope this helps you with your project and understanding how to calculate net acceleration. Remember to always consider all the forces acting on an object to find its net acceleration.
