Okay that makes a lot of sense :) Would the k of the spring then equal the k of the rope? So k(eff) = 2k ?

A massless spring of constant k=196 N/m is used to suspend the mass M=1.45 kg (including the pulley), as shown in the attached figure. What is the frequency of simple harmonic motion? Relevant equations f = 1/period T = 2pi*sqrt(M/k) Tension = 1/2Mg What I tried... T(tension on...

The equation worked, which is great, and the explanation was really helpful - I was just going to ask where the equation came from when i saw it - so thank you all!

Okay so i just realized that the speed I had found, 19.7 m/s, is for the fastest speed. Now I have no idea how to solve for the slowest speed

I think it means the slowest the car will be able to travel without sliding into the centre - it'll have to be moving fast enough to offset the other forces. That's how I took it at least. Part 2 of the question asks for the fastest speed, I figured I'd just try to figure out part 1 first:)

The problem: A car is traveling along a curve having a radius of 74.0m, banked at an angle of theta = 23 deg. The coefficient of static friction is 0.09. What is the slowest speed the car can negotiate the curve? Relevant equations: Fc = Fnet Fc = mv^2/r Fnet = [(tan(theta) +...
