A graph of real speed can have a section that's as steep as you want,
but it can never be a perfectly vertical section.
Any vertical line on a graph, even it it's only a tiny tiny section, means
that at that moment in time, the speed had many different values.
It also means that the speed took no time to change from one value to
another, and THAT would mean infinite acceleration.
gurlll this need way more points
Convection is the movement caused within a fluid by the tendency of hotter and therefore less dense material to rise, and colder, denser material to sink under the influence of gravity, which consequently results in transfer of heat
Car B, Car C, And Car E Are either speeding up or slowing down
Answer:
-5.6m/s²
Explanation:
Given parameters:
Initial speed = 11.2m/s
Time of running = 2s
Unknown:
Acceleration of the puppy = ?
Solution:
Acceleration is the rate of change of velocity with time.
So;
Acceleration = 
final speed = 0m/s
Acceleration = 
= -5.6m/s²
