Question

Adapt the velocity equation v=v0 + at to solve for average acceleration where the ball starts at t = 0.0 seconds and v0 = 0.00 meters/second

Answer 1

Answer:

The adapted expression for average acceleration is $a = \frac{v}{t'}$.

Explanation:

Let be $v = v_{o} + a\cdot t$, which can be adapted by using the following substitution:

$t = t'-t_{o}$

Where:

$t'$ - Final instant, measured in seconds.

$t_{o}$ - Initial instant, measured in seconds.

$v = v_{o}+a\cdot (t-t_{o})$

Where:

$v$ - Final velocity, measured in meters per second.

$v_{o}$ - Initial velocity, measured in meters per second.

$a$ - Average acceleration, measured in meters per square second.

Now, average acceleration is cleared:

$a = \frac{v-v_{o}}{t'-t_{o}}$

Given that $t_{o} = 0\,s$ and $v_{o} = 0\,\frac{m}{s}$, then:

$a = \frac{v}{t'}$

Answer 2

Answer:

a = (v-v0)      

     ____      where v = final velocity, v0

         t

Explanation:

Using algebra, , where v = final velocity, v0 = initial velocity, and t = time. So,

= -9.3 m/s2.
