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).

v2 = u2 + 2aS

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

v = 0

Thus; we will now have:

0 = u2 + 2aS

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

a = – (u2 / 2S)

In this case, the acceleration when the final velocity is 0 is given by a = – (u2 / 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.
