## Question

find the acceleration when the velocity is 0.

Read: calculate the molarity of the solution. (assume a density of 1.05 g/ml for the solution.)

## Solution

To find the acceleration when velocity is zero (0), we can apply one of the kinematic equations that relate final velocity (v), initial velocity (u), acceleration, and displacement (S).

v^{2} = u^{2} + 2aS

Therefore, if the final velocity (v) is zero (0), we will see that:

v = 0

Thus; we will now have:

0 = u^{2} + 2aS

After collecting like terms, and solving for a. The above equation will now become:

a = – (u^{2} / 2S)

In this case, the acceleration when the final velocity is 0 is given by a = – (u^{2} / 2S). However, if the initial and final velocities are zero, we will have acceleration equal to zero (0). This is because a=(v-u)/t. Thus, a = 0/t = 0.
