Angular acceleration is got by the expression
alpha = {(final angular velocity)2 - (initial ang velocity)2} / 2 theta.
final is 50 and initial is 100 rad/s. Theta is 50 x 2pi radian
Therefore required alpha = -50 x 150/200 pi = -75/2pi radian/s2
Negative sign indicates that the rotation is decelrated.

What is the meaning of sieving and give an example?
Seiving is a method that seperates a two subtances that is not join together it seperates uniformly
Which term describes a model in which a charge takes up no space and acts uniformly on it's surroundings?
point charge (apex)
What is punctuate distribution of cutaneous receptors?
Cutaneous Sensory Receptors are clustered in certain spots instead of being uniformly distributed. This clustering is called punctate distribution.
Is solutions heterogeneous?
A heterogeneous solution combines 2 or more solutions that are not chemically combined. A homogeneous solution is when the components are uniformly distributed.
Definition for solution?
a means of solving a problem or dealing with a difficult situation or a liquid mixture in which the minor component (the solute) is uniformly distributed within the major component (the solvent).
Is acceleration uniform in uniformly circular motion?
No, acceleration is not uniform in uniformly circular motion. In uniformly circular motion, the direction of the velocity vector is constantly changing, which means there is always a centripetal acceleration acting towards the center of the circle. This centripetal acceleration is not constant in magnitude, making the overall acceleration not uniform.
When does one feel the effects of velocity in a moving vehicle when it is moving uniformly or when its motion changes?
One feels the effects of velocity in a moving vehicle when its motion changes, such as when the vehicle accelerates, decelerates, or changes direction. When a vehicle is moving uniformly, there are no noticeable changes in speed or direction, so the effects of velocity are not as perceptible.
Direction of an object's velocity changes uniformly frome east to north What is the direction of acceleration?
North-west. More specifically, as the object's velocity direction changes uniformly from east to north, the acceleration and force producing this acceleration are both constant and changing direction uniformly from north to west.
What is the equation of uniformly accelerated motion?
Acceleration = change of speed / time
An object uniformly accelerates over a distance of 100 m in 20 seconds. What is the acceleration?
an object uniformly accerlerates over a distance of 100 m in 20 seconds. calculate the acceleration.
Is average acceleration equal to instantaneous acceleration for a uniformly accelerated car?
Average acceleration will be equal to instantaneous acceleration when an object has an uniform acceleration throughout its motion. Example : A car accelerating at 1m/s2 uniformly in a straight line.
When the bus decelerates uniformly at 5 point 3 m per s2 it slows from 8.5 m per s to 0 m per s what is the time interval of acceleration for the bus?
Vf = V0 + at --> 0 = (8.5 m/s) - (5.3 m/s²)t -> t = (8.5 m/s)/(5.3 m/s²) = 1.60377 s
Why is the acceleration of a body moving uniformly in a circle directed towards the centre?
The acceleration of a body moving uniformly in a circle is directed towards the center of the circle because it is constantly changing direction due to the change in velocity (even though the speed is constant). This change in direction results in a centripetal acceleration that keeps the body moving in a circular path.
What answer of A car accelerates uniformly from rest after five seconds its final velocity is twenty meter per second its acceleration during third second will be?
So it's acceleration is 4m/s2. So at any point because it says uniformly, it will be accelerating at 4m/s2 each second
What is the application of uniformly accelerated motion?
Uniformly accelerated motion is used to describe the motion of an object moving with a constant acceleration, such as a falling object under gravity. This concept is applied in physics to analyze and predict the motion of objects in free fall, projectile motion, and other scenarios where acceleration is constant. It helps in calculating the displacement, velocity, and acceleration of an object over time.
A vehicle accelerates uniformly from a speed of 4.0ms to a speed of 12ms in 6.0s. What is the vehicles acceleration?
4/3 ms-2.
What is uniformly accelerated motion?
It means that acceleration is constant. This meaning that velocity is varying with respect to time, we see this by this formula (v - v(initial) ) / t (Time).
