If a ferris wheel is rotating at constant speed is it moving at a constant velocity?
No. Velocity combines speed and the direction of motion.Constant velocity is constant speed in a straight line.In circular motion, the velocity is always changing even if the speed is constant,because the direction is always changing.
How to Convert revolution per minute to metres per minute?
You cannot. Revolutions per minute are a measure of angular velocity whereas metres per minute are a measure of linear velocity. There is no simple way to convert from one to the other. For example, at any given rpm, a point on the rim of a wheel is moving much faster than a point near the hub. You need the distance of a point from the axis of revolution (in metres) to convert angular speed to linear speed. If the distance from the centre is r metres then the point moves through 2*pi*r metres every revolution. ie 1 rpm = 2*pi*r linear metres per minute.
True or false the linear velocity of a point that is 1 ft from the center of a wheel rotating at 1 rev per sec is 2 pie ft per sec?
If this is a homework assignment, you really should consider trying it by yourself first, otherwise the value of the reinforcement of the lesson by the act of doing the homework will be lost on you.The circumference of a circle of radius 1 is 2 pi, therefore, a point on that circle rotating at a speed of 1 revolution per second has a linear (tangent) velocity of 2 pi feet per second.
A 12 inch grinding wheel has a surface speed of a mile a minute. What is its revolutions per minute?
A wheel with a diameter of 12 inches will have an angular speed of 560.2 revs per minute.
What is the linear speed of a bicycle that has wheels with a 2m circumference when its wheels rotate at 1 revolution per second?
2 meter circumference rotating 1 revolution per second produces a linear speedof 2 meters per second.The question can be slightly more exciting if you give the diameter of the wheel,or even its radius, instead of its circumference.
