    Calculus - Related Rates Problem

    Question: Two bikers leave a diner at the same time. Biker Slim rides at 85kmh [N] and Biker Haug rides at 120kmh [NE]. How fast is the distance between them changing 40 minutes after they left? I suggest looking at my photos of the triangles and such, as explaining it over text can be a bit...

    Needing help identifying a salt.

    So I recently did a titration lab with a monoprotic acid and sodium hydroxide. After using stochiometric ratios I found the molar mass to be around 175g/mol. It is possible I have a huge percentage error, but can anyone think of an acid that is monoprotic and is within the range of that molar...

    Amplitude and Vibrations in Springs

    Actually how about this for it. a) Ee = 0.46J b) Ee + Ek = Ee (max) Ee (max) - Ee (at x = 0.074m) = Ek ½(55)(0.13)2 - ½(55)(0.074)2 = ½(0.085)(v2) v = 2.78m/s c) Ek = Et ½mv2 = Et ½(0.085)(v2) = 0.46J v = 3.3m/s

    Amplitude and Vibrations in Springs

    So for c I decided at it's highest speed, Ee could equal 0 and for the other side I have Ee at it's highest and Ek = 0 so I ended up with. Ee = Ek ½mv2 = ½k(Δx)2 ½(0.085)v2 = ½(0.13)2(55) v = 3.3m/s b) I made Ee + Ek = Ee' + Ek' and for the beginning I had it equal zero for both when it is not...

    Amplitude and Vibrations in Springs

    Well for b what if I made Ee = Ek' + Ee' and if Ee on the left side is equilibrium then the it could equal and I could move the other one over and solve for that point. Basically making Ek = Ee. For c if it is at it's furthest point and highest speed could it be Ee = Ek but at a greater...

    Amplitude and Vibrations in Springs

    Homework Statement The amplitude of vibration of a mass on a horizontal spring experiencing SHM is = 0.13m. The mass is 85g and the force constant is 55N/m. a) What is the maximum elastic potential energy of the system. b) Find the speed of the mass when it's position is x = 7.4cm from the...

    Wanting clarification on Centrifugal force

    I was wondering if someone could help dissect my understanding of Centrifugal force and explain any errors in my logic. So imagining that I am driving a car and making a right turn. I make the right turn and am forced into the side of the door. I feel a force acting on me but after I make my...

    Centripetal Forces and Roller Coasters

    1. A roller coaster is designed with a clothoid loop that has a radius of 12 m at the top. For comfort, the apparent weight of a rider at the top of the loop must be 0.400 normal weight. What is the speed of the car at the top of the loop? 2. Fn = 0.400(Fg) Fn = 0.400(mg) mv2 / r = Fn + Fg...

    Centripetal Forces and Speed Question

    1. At a velodrome, bicycle riders race around the inside of a course shaped like a cup whose angle increases as the rider moves up the side. At one point the radius of the path is 50.0m and the track makes an angle of 45.0 degrees with the horizontal. If a rider is perpendicular to the track at...
