Homework Statement
A thought experiment. Imagine ants living on a merry-goround,
which is their two-dimensional world. From measurements
on small circles they are thoroughly familiar
with the number pi. When they measure the circumference
of their world, and divide it by the diameter, they...
I am majoring in physics with a minor in chemistry and I am wondering if taking two semesters of physical chemistry as an option for the minor would be redundant. From looking around I have seen that the first semester is watered down thermodynamics and the second semester is about quantum...
Homework Statement
A block of mass m sliding on a frictionless table is attached to a string that passes through a narrow hole through the center of the table. The block is sliding with speed v0 in a circle of radius r0. (Use any variable or symbol stated above as necessary.)
(a) Find...
Homework Statement
A nonuniform thin rod of length L lies on the x axis. One end of the rod is at the origin, and the other end is at x = L. The rod's mass per unit length λ varies as λ = Cx, where C is a constant. (Thus, an element of the rod has mass dm = λdx.)
Determine the gravitational...
Homework Statement
The Royal Gorge bridge over the Arkansas River is 310 m above the river. A 64-kg bungee jumper has an elastic cord with an unstressed length of 63 m attached to her feet. Assume that, like an ideal spring, the cord is massless and provides a linear restoring force when...
Homework Statement
A massless spring has unstretched length Lo = 0.45 m and spring constant k = 122.3 N/m. A block of mass m = 1.87 kg is attached to the spring, and a student stretches the spring to a length of L = 1.1 m. Then the student releases the block and it shoots upward. What is...
