DV=DX/dt=-5-3=-8/2=-4 Da=-dv/dt=-4-12=-16 we are not dividing with t because we have already found the displacement change at that time

A body moving with uniform acceleration has a velocity of 12.0 cm/s in...
Given data:
Initial velocity, u = 12.0 cm/s (in the positive x-direction)
Initial position, x1 = 3.00 cm
Final position, x2 = -5.00 cm
Time interval, t = 2.00 s

To find: Magnitude of acceleration, a

We can use the following kinematic equation to solve this problem:
x2 = x1 + ut + (1/2)at^2

Substituting the given values into the equation, we have:
-5.00 cm = 3.00 cm + (12.0 cm/s)(2.00 s) + (1/2)a(2.00 s)^2

Simplifying the equation:
-5.00 cm = 3.00 cm + 24.0 cm + a(2.00 s)^2
-5.00 cm = 27.00 cm + 4.00 as^2
-32.00 cm = 4.00 as^2

Dividing both sides of the equation by 4.00 s^2, we get:
-8.00 cm/s^2 = a

Since we are asked to find the magnitude of acceleration, we take the absolute value of the result:
|a| = |-8.00 cm/s^2| = 8.00 cm/s^2

Therefore, the magnitude of the acceleration is 8.00 cm/s^2.

Hence, the correct answer is option A, -16.0 cm/s^2.
