An electric fan is turned off and its angular velocity decreases uniformly from 550 rev min to 200 in rev per min time interval of length 4.50 sec Find the angular acceleration in meters per sec sq?
(550 - 200) rev per minute = -350 rev per minute / 60 sec per minute = (-35/6 rev per second) change in angular velocityAngular acceleration = (change in angular velocity) / (time for the change) =(-35/6 rev per second) x (2 pi radians per rev) / 4.5 seconds = -8.1449 radians per second2("Meters per sec sq" can't be a unit of angularacceleration, since angles can't be measured in meters.)
What is the angular size of a circular object with 1 inch diameter viewed from 4 yards?
To find the angular size, we need to convert the distance to the object into radians. 4 yards is approximately 12 feet or 144 inches. The angular size can be calculated as the diameter of the object (1 inch) divided by the distance to the object (144 inches), which equals approximately 0.0069 radians.
How can i find velocity when given force and time?
If you have the mass, you can find the acceleration from Newton's Second Law, a=F/m where a is the acceleration, m is the mass, and F is the force. Then the velocity is given by the standard formula v=vo+at where v is the final velocity, vo the velocity at t=0, probably 0 in your case. If so v=at.
How do you find the arc length formed by a central angle x?
The arc length is equal to the angle times the radius. This assumes the angle is expressed in radians; if it isn't, convert it to radians first, or incorporate the conversion (usually from degrees to radians) in to your formula.
How do you find velocity with a known time and distance?
Velocity equal distance divided by time. For example, an object that traveled 5 metes in 10 seconds had a velocity of 5/10 meters per second which is .5 meters per second. Velocity is speed in a direction. Sometimes a navigate or positive number is sufficient as the direction. Other times you will need to be more specific, such as .5 meters per second East or 1.3 meters per second 30 degrees East of North.
How do you find the angular velocity of second hand of a watch?
The angular velocity of the second hand of a watch can be found by calculating the angle it rotates through in a given time period, typically one minute, and then converting it to radians per second. This can be done using the formula: angular velocity = (2Ī/60) radians/second, as the second hand completes one full rotation in 60 seconds.
How do you find tangential velocity?
Tangential velocity can be found by multiplying the angular velocity (in radians per second) by the distance from the axis of rotation to the point of interest. It represents the speed at which an object is moving around a circle or rotating about a point.
A wheel is rotating at 250 revolutions per minute find the angular speed in radians per second?
1 revolution = (2 pi) radians1 minute = 60 seconds250 rpm = [ (250) x (2 pi) radians ] per [ 60 seconds ]= 26.18 radians per second (rounded)
Why do planets rotate around the sun in the same direction?
Planets in our solar system rotate around the sun in the same direction due to the way the solar system formed from a spinning cloud of gas and dust. This rotation direction was set as the planets coalesced from this material in a common plane of orbit, resulting in the same rotational direction.
Find the angular displacement of 15.2 revolutions round to the nearest tenth?
It is 95.5 radians.

How do you find torque of single phase synchronous motor?
You can use the relation that power equals torque times angular velocity. You start from the speed (rpm) and the horse power times 746 which gives the mechanical power in watts. To use the formula you have to use consistent units, which means torque is in Newton-metres and the angular velocity is in radians/second, in other words the rpm times 2.pi / 60. So the torque in Newton-metres is the power (watts) divided by the shaft speed in radians per second. T = (HP x 746) / (rpm x 2 x pi / 60) So if you know the speed and the power, you can find the torque.
Find the angular velocity of r equals 8.0?
Assuming that "r" is the radius, that simply isn't sufficient information to calculate angular velocity.
Hoe to calculate velocity of a rotating member?
The velocity of a rotating member can be calculated using the formula v = rĪ, where v is the linear velocity, r is the radius of rotation, and Ī is the angular velocity in radians per second. Multiply the radius of rotation by the angular velocity to find the linear velocity of the rotating member.
How we find the Direction of angular velocity of a rotating wheel?
The direction of angular velocity in a rotating wheel can be found using the right-hand rule. If you curl your fingers in the direction the wheel is rotating, then your thumb points in the direction of the angular velocity vector. This rule helps determine whether the angular velocity is clockwise or counterclockwise relative to the rotation.
What is the angular size of a circular object with 1 inch diameter viewed from 4 yards?
To find the angular size, we need to convert the distance to the object into radians. 4 yards is approximately 12 feet or 144 inches. The angular size can be calculated as the diameter of the object (1 inch) divided by the distance to the object (144 inches), which equals approximately 0.0069 radians.
What is the ball's angular velocity A ball at the end of a string of length 0.75 m rotates at a constant speed in a horizontal circle?
The ball's angular velocity is the rate of change of its angular displacement over time. In this scenario, since the ball is rotating at a constant speed in a horizontal circle, its angular velocity remains constant as well. Angular velocity (Ī) can be calculated by dividing the speed of the ball by the radius of the circle.
