I have a book that gives a formulae Angular Speed as same as the Angular Velocity...is that true?
From what i understand, speed is a scalar quantity...so it only have the magnitude value while velocity is a vector quantity which also shows the direction.
Also, will the average angular...
Hey i have this problem and would like to know if what i got is somewhere in the right direction. Any help would be GREATLY appreciated
A gymnast is performing a forward double somersault.
The gymnast’s initial angular velocity is 0 rad/s.
The gymnast generates a 115 N-m torque.
The...
Hello,
I need to confirm my solution to this problem: A thin rod of length l stands vertically on a table. The rod begins to fall, but its lower end does not slide. (a) Determine the angular velocity of the rod as a function of the angle \phi it makes with the tabletop. (b) What is the speed...
A small mass m is attached to a point O by an inextensible string of length a. The mass is held with the string taut, at the same level as O, and released. Determine the angular velocity of the mass when the string makes an angle \thetawith the downwards vertical. From this relationship...
consider a body rotating with a constant angular velocity 'w' along the z axis of the space reference frame.the centre of mass of the body is at the origin of the space system of coordinates.
now since 'w' is a vector, it must transorm according to the rotation matrix
R (in this case as...
I can't find formula for determing the number of rotations a wheel makes in one minute.
Diameter = 26"
Traveling at 20 feet per second.
is there a formula for RPM?
Also need the formula to determine angular velocity.
thanks
A Ferris wheel has a radius of 8 meters and rotates once every 15 seconds.
A 10:1 scale model of the Ferris wheel also rotates once every 15 seconds.
Which has the higher Angular Velocity?
Solution: angular velocity = Change in rotation/change in time
Do I use the formula v = rw...
here is the problem:
An airplane propeller is 2.08 m in length (from tip to tip) and
has a mass of 117 kg. When the airplane's engine is first started,
it applies a constant torque of 1950 N*m to the propeller, which starts from rest.
-What is the angular acceleration of the propeller...
if a disk which is initially spinning with an angular velocity,w, radians per second is pushed with an initial linear velocity of v, what is the resultant motion? assume a kinetic friction of mu normal to the disk
i would love to see how this problem is solved. it seems real...
If a top is spinning in the horizontal x,y planes in a counter-clockwise motion, the vector of its angular velocity and acceleration is perpendicular to that plane, specifically in the positive z direction.
Is there any specific reason for direction? My book states that the vector must be...
Can somebody tell me what is the angular velocity of an electron (more or less) around the nucleus. (it doesn't matter whether it's one in the most inner shell or the most outter, I just need an average value)
thanks
Dear all
By right - hand rule, if circular motion of the object is anti-clockwise in horizontal circle, so that the centripetial force of it will upward in vertical. In addition, the centripetial force is larger that gravity, then the object will move upward in vertical. Do you agree with my...
An alternator attached to a water turbine generates 35 Watts given 50 feet of head and 10 gallons per minute. Assuming that the efficiency of the alternator is 50%, is it possible for me to find the angular velocity from this information?
If so, how would I do it?
I have started this billiards, and am very confused by one thing.
The ball has a mass of M, radius R, and mement of inertia about center of mass I=2/5MR2 .
The ball is struck in the center and slides with a initial velocity. Here is what I am having trouble with, if you could give me a hint to...
Can anyone tell me the difference between "rotational velocity" and "angular velocity"?
I got that angular velocity is the dimension of angle/time, but rotational velocity is the dimension of rotations/time.
Will appreciate it if you can also provide me with some references defining the...
Hi all, recently joined and having abit of trouble with a problem (several actually but I managed to figure out how to get started on one of them).
In any case the problem says:
Four thin, uniform rods each of mass M and length d = .75 m, are rigidly connected to a vertical axle to form a...
