By definition, speed is the integral of acceleration with respect to time.
We have then:
As the acceleration is constant, then integrating we have:
Where,
vo: constant of integration that corresponds to the initial velocity
We observe then that the speed varies linearly when the acceleration is constant
.
Therefore, for constant acceleration, the velocity is changing.
Answer:
an object with a constant acceleration always have:
A. changing velocity
Its acceleration is 10ft/ sec
The shades are very different
B. If all plants are watered at least once a day then they will all grow at least 1 cm a day.
All plants grow at different rates.
Hope this helps! XD
