Circular motion

A 5.0-m-diameter merry-go-round is initially turning with a 4.0 s period. It slows down and stops in 20 s. Before slowing, what is the speed of a child on the rim? (in m/s)

Magnitude of Horizontal / Vertical Acceleration

A block of mass m1 is attached to a massless, ideal string. This string wraps around a massless pulley and then wraps around a second pulley that is attached to a block of mass m2 that is free to slide on a frictionless table. The string is firmly anchored to a wall and the whole system is frictionless. Use the coordinate sys ...continues

Problem 8.10

Please do not place your response in a .pdf or .cdx format, but Word documents are okay. Thanks! Here's the actual problem: An 95.0 kg spacewalking astronaut pushes off a 630 kg satellite, exerting a 80.0 N force for the 0.550 s it takes him to straighten his arms. How far apart are the astronaut and the satellite after 1. ...continues

Conservation of Momentum

An astronaut performs maintenance work outside her spaceship when the tether connecting her to the spaceship breaks. The astronaut finds herself at rest relative to the spaceship, at a distance x1 from it. To get back to the ship, she decides to sacrifice her favorite wrench and hurls it directly away from the spaceship at a spe ...continues

Collision at an Angle (Find Speed)

Find the speed of the joined cars after the collision detailed in the attachment (includes diagram)

loaded Sullivan's perfect s ratchet

Show that in the case of zero external force the equation v=(fL/kT)^2 D/L (e^(fL/kT) - 1 - fL/kT)^-1 reduces to 2D/L. Then show that at high force(but still smaller than (epsilon/L)) the equation reduces to v=(fL/kT)^2 D/L (e^(-fL/kT))
