The question was something like that I'm not sure and also if you through a ball straight up and its at the top were its velocity is 0 is its acceleration 0 also??

SI means International System of Units. Some of the common standard units are:
length = meter
mass = kilogram
electric charge = coulomb
time = second
When you throw the ball up in the air, it is slowing down at a constant rate until it gets to the top of its flight (constant negative acceleration) and then speeding up in a downward direction at a constant rate after it gets to the top of its flight (constant negative acceleration). The acceleration of a ball throughout its whole flight remains constant, and is NEVER zero. If it was zero at the top, the ball would never fall back to the ground. Zero velocity and zero acceleration means the ball will sit in that position forever.

SI is the abbreviation of international standard system in French. There are eight simple units in SI. A is not the measure of distance, it is the measure of electrical current. A is the first letter of Ampere, who defined current as Q/t.

those i've got taken have been actual a attempt of intelligence. being waiting to discover varieties in pictures and are available up with the subsequent logical answer, observe institutions, hit upon varieties interior of a series of numbers,math complications, and so forth...i could want to think of they're precise (I did ok every time i became examined) in spite of the undeniable fact that as Pope reported your ideas set on the time performs a extensive component, being nicely rested formerly taking the attempt made a distinction of 18 pts between my worse and ultimate score.

If the acceleration on the ball was zero, it would stay there and not fall down again, so no, the acceleration is constant and equal to gravity (9.81 m/s^2).
