Question. The collar C is moving downward with an acceleration of 1 m/s2. At the instant shown, it has a speed of 2 m/s which gives links CB and AB an angular velocity ωAB = ωCB = 10 rad/s. Find the angular accelerations of AB and CB at this instant.
Suggestions:(A) Calculate aAB and aCB(B) aB = aC + aB/C)t + aB/C)n(C) aB/C)t = raCB(D) aB/C)n = rωCB2
A 56.0 kg person jumps from rest off the 9.0 m high tower straight down into the water. Neglect air resistance throughout the descent. She comes to rest 3.40 m under the surface of the water. Find out the magnitude of the average force that the water..

Six artificial satellites complete one circular orbit around a space station in the same amount of time. Each satellite has mass and radius of orbit. The satellites fire rockets that provide force needed to keep a circular orbit around the space stat..
A child and sled with a combined mass of 49.20 kg slide down a frictionless hill that is 7.38 m high. If the sled starts from rest, what is its speed at the bottom of hill.
A crate of 30.2- tools rests on a horizontal floor. You exert a regularly increasing horizontal push on it and observe that the crate just begins to move while your force exceeds 319. After that you must reduce your push to 227 to keep it moving at a..
You can turn the crank at a maximum rate of 3 turns per second, but hand crank is connected to the coil through a set of gears that makes the coil spin at a rate 6 times larger than the rate at which you turn the crank. What is the maximum emf you ca..
