Average speed during the deceleration is 1/2(19 + 0) = 9.5 meters per second.
Time of deceleration is (31 / 9.5) seconds.
Magnitude of deceleration is (change of speed) / (deceleration time) = 19 / (31/9.5) = (19 x 9.5) / 31 = 5.823 m/s2
(The acceleration is the negative of this number.)
-- The magnitude of acceleration is equal to the time rate of change of speed. -- The magnitude of acceleration is equal to the time rate of change of the magnitude of velocity. -- Acceleration and velocity are both vectors.
No. Acceleration is (change of velocity) divided by (time interval in which it changed). If velocity doesn't change, then there is no acceleration.
It is called acceleration.
It is called acceleration.
That's the magnitude of its acceleration.

magnitude of acceleration=change of velocity/time invertal
No. Speed is the magnitude of velocity and acceleration is the change of velocity in time.
No. Acceleration is (change of velocity) divided by (time interval in which it changed). If velocity doesn't change, then there is no acceleration.
It is called acceleration.
