Want this question answered?
Average Velocity
(change in distance) divided by (time interval) = the object's average speed during that time interval.
To get average speed, just divide distance by time. In this case, you divide whatever distance an object moves during the 11 seconds, by the 11 seconds.
Acceleration. Deceleration is a decrease of speed during a given interval of time.
Answer: The average speed of the object is 1.95 m/s. Explanation: Distance traveled by an object in the first interval, = 2 m Time is taken in firsts interval = 2 s Distance traveled by an object in the second interval, = 80 mm Time taken in second interval = 40 s The average speed of the object is 1.95 m/s.
The average power during the time interval.
i think no
yes

I went to get some more popcorn during the interval.
During the interval, the actors had a rest before the next act in the play.
The RR interval of ECG vary during normal respiration because of the sinus arrhythmia.
Average acceleration during the time interval = (change on speed) / (time for the change) =(98 - 121) / (12) = -23/12 = negative (1 and 11/12) meters per second2
