Hi. When a plane travels in a vertical circular loop, what is the provider of the centripetal force, required to produce the circular motion? At the top of the loop, there is gravity acting towards the center of the circle, so id assume that this is part of it, but what about at the bottom...

Homework Statement Explain why applied force is plotted on the vertical axis of the graph even though it is the independent variable in a Hooke's Law experiment (involving a mass being attached to the spring) Homework Equations Fx = kx The Attempt at a Solution Maybe it's because...

1. Homework Statement . The correct answer is E 2. Homework Equations :Procedure from our text: "Step 1. Determine the differential equation for the given family F(x, y,C) = 0. Step 2. Replace y' in that equation by −1/y'; the resulting equation is the differential equation for the family of...

I learned that vertifcal tangents occur at a parametric curve if the derivative of the curve is undefined. That is given dy/dx = dy/dt / dx/dt, a vertical tangent occurs when dx/dt = 0. I don't understand why this is so. I know that vertical tangents occur when the slope is infinite, but...

Homework Statement A mass m is thrown vertically from the surface of the Earth with a velocity v0. Find a function that describes the velocity v of the mass m in dependence of its distance z from the center of the earth. Homework Equations m*z'' = -G* m*M / z^2 z'' = dv / dt G =...

Loop the Loop problem help. The Problem says that there is a little car going at an initial speed of 4 m/s while entering a vertical loop the loop. Then all it wants is the largest possible radius of the loop that the car can still remain on the track at all times. I don't understand, the...

Solved the problem.

Surprisingly, very few humans can jump more than 2 feet (0.6 m) straight up. Solve for the time one spends moving upward in a 2-foot vertical jump. Then double it for the "hang time" - the time one's feet are off the ground. b) Calculate the vertical height of Michael Jordan's jump when he...

Okay, I need to demonstrate circular motion of this ride(only the vertical rotation, not the spinning disc that holds the people): http://www.sixflags.com/parks/stlouis/Rides/excaliber.html I only really understand circular motion vaguely, I'm not sure whether this is uniform or...

An 8.00 kg stone rests on a spring. The spring is compressed 7.0 cm by the stone. (a) What is the spring constant? 11.2 N/cm (b) The stone is pushed down an additional 30.0 cm and released. What is the elastic potential energy of the compressed spring just before that release? 76.7 J...

Hello there! My study mate and I have been trying to figure this one out but have not had success. This is the problem we would appreciate to get some help with: A ball with mass of 20 grams is attached to a robe and is revolving vertikal in a circle. There is no energy beeing added to...

the equation is: x^2 + xy + y^2 = 25 my method was to implicitely differentiate and then set the numerator = 0 to get points of horizontal asymptotes, and then set the denominator = 0 to get the points for the veritcal asymptotes. when i use implicit differentiation i get: y' = (-2x...

This is a example in my book a rational function like f(x) = [(x+2)(x-5)]/[(x-3)(x+1)] has vertical asymptotes at x=3 and x=(-1) Is all you do is switch the addition and subtraction signs in [(x-3)(x+1)]? The same equation has a horizontal asymptotes at y=1, which i can't seem to...

Hello all, This is (I think) one of the more popular introductory physics questions. Someone ties a bucket to a rope, puts some water in it and swings it around in a vertical circle with relatively constant speed. When the bucket is directly above the person's head, the water stays in the...

a mass is attached to a spring and released. it then oscillates in simple harmonic motion. what is the transformation of energy? i understand how it works horizontally (max Ee at the 2 ends, max Ek at the equilibrium position), but how does it work vertically now that Eg is also present...

An object falling from some point in the air (near the surface) with air friction, R = kv. So, m\frac{dv}{dt} = mg - kv Seperate variables for \int \frac{m}{mg - kv} \cdot dv = \int dt and for the LHS I use integration by parts, so, (m)(mgv - \frac{1}{2}kv^2) - \int mgv - \frac{1}{2}kv^2...

In its final trip upstream to its spawning territory, a salmon jumps to the top of a waterfall 1.9m high. What is the minimum vertical velocity needed by the salmon to reach the top of the waterfall? There seems to be some piece of information missing. I know that: a = 9.8 m/s^2 dy = 1.9m...

Okay, I am messing something up here. I think it's my logic. Given k=2.5 * 10^3 N/m Find how much mass would have to be suspended from the vertical spring to move it 6.0 cm I get W=1/2kx^2=.5(2500)*(.06m)^2=4.5J I think that's right. Then I do W=F*d=m*a*d or...
