A particle of mass m is traveling along the x-axis with a constant horizontal velocity v0i. When the particle passes through the origin, it experiences a Drag Force which is proportional to the square of the particle's speed (F[SIZE="1"]d = - b/v^2i... drag coefficient b...
As most of you know, the drag force equation is Fd=1/2*p*Cd*V^2*Cd*Ac.
At terminal velocity, Fd equals weight. If you find the value of all the variables except Cd and V, you still won't have anything. But the terminal velocity equation is Vt= sqrrt of 2weight/p*Cd*Ac. So if V is terminal...
Hello everyone. I have researched from the internet that the drag force equation for projectile motion is either F= C p a v^2 or F= 0.5 C p a v^2. Which one is the correct one? The initial speed I am dealing with is about 20m/s. And what's the value for C for a normal tennis ball. Other sites...
Hello, please help me I have a question regarding drag force and Newton's law of motion.
This is quotes from online pdf files from University of Toronto Scarborough.
"the terminal velocity is F/b , where b is drag constant
Let’s solve the equation of motion and see how
this is reflected...
I have a question about a physics problem, this comes from Barger's Classical Mechanics: A boat is slowed by a drag force, F(v) and its velocity decreases according to the formula v=c^2(t-t_{1})^2 where c is a constant and t_{1} is the time at which it stops. Find the force F(v) as a function...
Can anyone Please help me on this. I am totally stuck at this question .
thanks...

The first part of a pretty involved, 8 part question on modelling drag force states: "A 0.142 kg ball has a terminal speed of 42.5 m/s. If a ball experiences a drag force of R=CV^2, what is the value of the constant, C?
I know this is a ridiculusly easy problem, but our text doesn't cover...
free fall with drag force
If the equation F=-bv^2 describes the drag force of an object...then the differential equation for the object's motion would be:
dv/dt= -g+bv/m
or is it...
dv/dt= g-bv/m
After solving the equation, should I get...
V=mg/b[1-e^(-bt/m)]
Also, does this...
Can anyone give me a relationship for the turbulent drag force on an object with a cross sectional area A and a speed v in a medium with density p please?
Thanks
