AI Thread Summary
The discussion focuses on calculating the projectile motion of a baseball hit at an initial velocity of 110 mph at a 45-degree angle, factoring in wind speeds ranging from 40 to -40 mph. The key equations involve determining the acceleration in both the x and y directions, with the y-direction influenced by gravity and air drag, while the x-direction is affected by the initial velocity and air drag. The initial x-velocity can be calculated using 110*cos(45), and the y-velocity using 110*sin(45) minus gravitational acceleration. The conversation highlights the need for a time-based model to accurately graph the trajectory. Understanding these equations is essential for developing the desired program.

Someone please help me, I need help I'm writing program that graphs a baseball that has been hit with inital velocity 110 mph as an angle 45 degrees with a wind of 40 to -40 mph. All I really need is the equation of motion for a baseball with with this head or tail wind please please someone help me.

I know from my physics book that the acceration in the y-direction is a=g-(air drag) v^2. I have the value of the air drag but how do I find the accerlation the the x-direction. I'm assuming that the wind is acting in that direction.

Thanks

I have no idea about quantifying miles because I am an aussie and we use metres and I am 18 so i wasnt around when they had miles...

in the x direction you have an initial velocity of 110*cos45 essentially the only thing that will stop it in terms of x wil be drag so (110cos45) - air drag will be x (assuming you have a formula for air drag in terms of distance or time)... the y component will be 110*sin45 - g the problem is if your going to modle the tagectory you need something in terms of time. i don't know exactly coz you havnt given much info... hope it helps

Thread 'Variable mass system : water sprayed into a moving container'

Starting with the mass considerations #m(t)# is mass of water #M_{c}# mass of container and #M(t)# mass of total system $$M(t) = M_{C} + m(t)$$ $$\Rightarrow \frac{dM(t)}{dt} = \frac{dm(t)}{dt}$$ $$P_i = Mv + u \, dm$$ $$P_f = (M + dm)(v + dv)$$ $$\Delta P = M \, dv + (v - u) \, dm$$ $$F = \frac{dP}{dt} = M \frac{dv}{dt} + (v - u) \frac{dm}{dt}$$ $$F = u \frac{dm}{dt} = \rho A u^2$$ from conservation of momentum , the cannon recoils with the same force which it applies. $$\quad \frac{dm}{dt}...
