How can I solve this potential energy problem with an elliptical equation?

AI Thread Summary
To solve the potential energy problem involving the elliptical equation (f(x)/fmax)^2 + (x+d/d)^2 = 1, one can manipulate the equation to isolate F(x) and apply the potential energy formula U = Fd. The work done on the arrow can be calculated using W = U1 - U2, where U1 is zero since the arrow starts at rest. To determine the maximum range, the initial velocity can be derived from the potential energy, and the launch angle can be calculated using tanθ = (x+d)/d. Consulting a math or physics tutor may provide additional insights and methods for solving the problem.

I am faced with the elliptical equation (f(x)/fmax)^2+(x+d/d)^2=1.
In this equation, f(x) is the draw force of a bow on an arrow, d is distance,x is displacement of bow string. We are given values of d,fmax,and mass and told to calculate the work done on the arrow, and its maximum range. I have no idea how to go about this because of the form of this equation. Can someone lead me in some direction, any direction?

move the x term to the right side, then take the square root of both sides. after than you can multiply fmax on both sides and you are left with a nice function.
 


One possible way to solve this potential energy problem with an elliptical equation is to use the formula for potential energy in terms of force and displacement. This formula is given by U = Fd, where U is the potential energy, F is the force, and d is the displacement. In this case, we can rewrite the equation as (F(x)/Fmax)^2 + (x+d/d)^2 = 1, and then solve for F(x) using algebraic manipulation. Once we have the value of F(x), we can substitute it into the formula for potential energy and solve for U.

To calculate the work done on the arrow, we can use the formula W = U1 - U2, where W is the work done, U1 is the initial potential energy, and U2 is the final potential energy. Since the arrow starts at rest, U1 = 0. We can then use the value of U calculated above to find U2, and then plug both values into the formula to find the work done.

To find the maximum range, we can use the formula for range in projectile motion, R = (v^2sin2θ)/g, where v is the initial velocity, θ is the angle of launch, and g is the acceleration due to gravity. In this case, we can calculate v using the formula v = √(2U/m), where m is the mass of the arrow. We can also find the angle of launch using the equation tanθ = (x+d)/d. Once we have calculated both v and θ, we can plug them into the range formula to find the maximum range.

It is important to note that there may be other approaches to solving this problem, and the specific method used may depend on the given values and the context of the problem. It may also be helpful to consult with a math or physics tutor for further guidance and clarification.

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}...
