So F + M g = Acp. Alright, thanks.

Homework Statement A 1.11 kg disc is whirled in a vertical circle with radius 0.680m about a fixed point. Find the tension at the top if the speed at the top is 8.76 m/s. Homework Equations F= ma F= m* Acp Acp= m(w^2*r) [b]3. The Attempt at a Solution I figured centripetal...

A. The magnitude of the acceleration has to be equal because the tension in the strings of the pulley would have to be equal B.The center of the mass does not accelerate because there is no force acting on it. C.The tension in string 1 is greater than m1g, because it would have to be in...

Homework Statement These are true/ false questions, equal to, >, or < A frictionless, massless pulley is attached to a ceiling, Mass m2 is greater than mass m1. A. The magnitude of the acceleration of m2 is ... the magnitude of the acceleration on m1. B. The center of mass accelerates...

I figured out what I was doing wrong, I calculated the Acp wrong.

Homework Statement An 80 kg pilot, makes a loop the loop in a jet, the jet maintains a constant speed of 305 m/s and the radius of the loop is 1.900km. What is the apparent weiht that the pilot feels( Force) at the bottom of the loop the loop. Homework Equations Acp=w^2/r w=(v/r) F= ma...
