an object has an acceleration of 12.5 m/s2. if the net force experienced by the object is decreased by a factor of 4.5 then what is the new acceleration

a=F/m

F1=F/4.5 => a1=a/4.5=12.5/4.5=2.78 m/s^2

To find the new acceleration, we need to use Newton's second law of motion, which states that the force acting on an object is equal to its mass multiplied by its acceleration:

F = m * a

Where:
F = Net force experienced by the object
m = Mass of the object
a = Acceleration

Since we are given that the net force is decreased by a factor of 4.5, the new net force (F') can be calculated as:

F' = F / 4.5

The acceleration (a') can be calculated by rearranging the equation:

F' = m * a'
a' = F' / m

Substituting the values into the equation, we can find the new acceleration:

a' = (F / 4.5) / m

Given that the original acceleration is 12.5 m/s^2, let's say we assume the mass of the object is 1 kg:

a' = (12.5 m/s^2 / 4.5) / 1 kg
a' ≈ 2.78 m/s^2

Therefore, the new acceleration is approximately 2.78 m/s^2.

To find the new acceleration of the object when the net force is decreased by a factor of 4.5, you can use Newton's second law of motion, which states that the acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass.

Mathematically, this can be represented by the equation: F = m * a

Where:
F is the net force applied to the object,
m is the mass of the object, and
a is the acceleration of the object.

Since we have the initial acceleration (12.5 m/s^2), we can rearrange the equation to solve for the new acceleration.

a = F/m

Let's assume that the mass of the object remains constant.

If the net force is decreased by a factor of 4.5, it means the new net force (F_new) will be 1/4.5 times the original net force (F).

F_new = F / 4.5

Now we can substitute this value into the rearranged equation for acceleration:

a_new = (F / 4.5) / m

Since we don't have the specific value of the net force or the mass, we can't determine the exact new acceleration. However, you can plug in the appropriate values for the net force and mass to calculate the new acceleration using the formula above.
