(550 - 200) rev per minute = -350 rev per minute / 60 sec per minute = (-35/6 rev per second) change in angular velocity
Angular 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 are three components needed to find an object acceleration?
Using the definition of acceleration as change of speed / time, you basically need to know: * A time interval during which the object accelerates. * The velocity at the beginning of this time interval. * The velocity at the end of this time interval.
Which of these is an increase of speed during a given interval of time?
positive acceleration
What happens to the confidence interval as the standard deviation of a distribution decreases?
It goes up.
What is the displacement of the train as it accelerated uniformly from 11 meter per second to 33 meter per second in a 20 second interval?
231m
What happens to R-R interval after exercise?
During exercise an increase in heart rate corresponds to a shortening of the cardiac cycle (RR interval decreases). Most of this shortening occurs in the TP interval. The QT interval also shortens, but only slightly. then the interval shortens as the heart rate increases.
Is average acceleration equal to instantaneous acceleration for a uniformly accelerated car?
No, average acceleration is the overall change in velocity over a specific time interval, whereas instantaneous acceleration is the acceleration at a specific moment in time. For a uniformly accelerated car, the average acceleration is constant over the entire interval, but the instantaneous acceleration can vary at different points during that interval.
What is uniformaly accelerated motion?
Uniformly accelerated motion refers to the situation where an object's velocity changes by the same amount in each equal time interval, leading to a constant acceleration. This means that its speed increases or decreases by a fixed value per unit time. This type of motion is described by the equations of motion derived from Newton's laws of motion.
What is the average acceleration during the time interval 0 seconds to 10 seconds?
The average acceleration during the time interval from 0 to 10 seconds is the change in velocity divided by the time interval. If you provide the initial and final velocities during this time interval, we can calculate the average acceleration for you.
What happens to the confidence interval as the mean decreases?
The confidence interval is not directly related to the mean.
How to find acceleration?
Acceleration can be calculated by dividing the change in velocity by the time taken to make that change. The formula for acceleration is: acceleration = (final velocity - initial velocity) / time. Acceleration is a vector quantity, meaning it has both magnitude and direction.
How do you calculate a objects acceleration?
Acceleration = (change in speed) divided by (time interval)
What is the formula in finding the acceleration of an object?
The formula for acceleration is acceleration = change in velocity / time interval. It can also be written as a = (v_f - v_i) / t, where a is acceleration, v_f is the final velocity, v_i is the initial velocity, and t is the time interval.
Which is an increase of speed during a given interval of time?
Acceleration is an increase in speed during a given interval of time. It is the rate of change of velocity with respect to time.
What is the formula to determine the acceleration of an object moving in a strait line?
The formula to determine acceleration is acceleration = change in velocity / time taken. It can also be written as a = (v2 - v1) / t, where a is acceleration, v1 is the initial velocity, v2 is the final velocity, and t is the time taken.
What is An increase of speed during a given interval of time is called negative acceleration?
Actually, an increase in speed during a given interval of time is called acceleration, not negative acceleration. Negative acceleration, also known as deceleration, refers to a decrease in speed over time.
What increases speed during a given interval of time?
acceleration
An increase of speed during a given interval of time is called negative acceleration?
No, an increase in speed during a given interval of time is called acceleration. Negative acceleration, also known as deceleration, refers to a decrease in speed over time.
