yes, many answers in applied maths come out as negative, it just means that the force or object is slowing down or reversing. in this case there is a negative acceleration as its slowing down

When an object's initial velocity is less than its final velocity what does that indicate?
AccelerationWhen the velocity of an object increases or decreases, that means it has accelerated. Acceleration is defined as the rate of change of velocity.If an object's final velocity is greater than its initial velocity, that indicates positive acceleration. If an object's final velocity is less than its initial velocity -- if, say, it slows down and comes to a stop -- then that indicates negative acceleration. Deceleration is another way of saying negative acceleration. But . . .It is good idea to avoid using the term deceleration, because an object that is experiencing negative acceleration may slow down, come to a stop momentarily, and then reverse direction and speed up -- IN THE OPPOSITE DIRECTION!You can think of it this way: When an object is slowing down, its acceleration is in the direction opposite to its motion. We think of that as negative acceleration.
What formula do you use to calculate the acceleration of an object moving in a straight line?
Acceleration = Final velocity - Initial velocity / time
How do you find final Velocity of an object?
The final velocity is (the initial velocity) plus (the acceleration multiplied by the time).
How do you find initial acceleration.?
The initial acceleration of an object can be found by calculating the change in velocity over time. This can be done by dividing the final velocity by the time taken to reach that velocity. The formula for initial acceleration is: initial acceleration = (final velocity - initial velocity) / time.
If you know the distance traveled and the time traveled can YOU determine an object and ACCELERATION?
no, you need to know its initial velocity to determine this; if initial velocity is zero then distance is 1/2 acceleration x time squared
When an object's final velocity is less than its initial velocity it has what kind of acceleration?
Negative acceleration.

When the acceleration is zero what can you say about the velocity of an object?
When acceleration is zero, the object's velocity can still be changing if the initial velocity is not zero. However, if acceleration is zero and the initial velocity is also zero, then the object's velocity will remain constant.
Can an object's acceleration be a negative number?
Yes, an object's acceleration can be a negative number if it is experiencing deceleration or moving in the opposite direction of its positive acceleration. Negative acceleration represents a decrease in velocity over time.
What information do you need in order to find a object's acceleration?
To find an object's acceleration, you need its initial velocity, final velocity, and the time it takes to change from the initial velocity to the final velocity. The formula for acceleration is (final velocity - initial velocity) / time elapsed.
If an object is accelerating what equation relates the acceleration of that object the initial velocity and the final velocity and time?
The equation that relates acceleration (a), initial velocity (u), final velocity (v), and time (t) for an object under constant acceleration is: v = u + at.
What To calculate an object's acceleration you need to know?
To calculate an object's acceleration, you need to know its initial and final velocity, as well as the time taken to change velocity. Acceleration is calculated using the formula acceleration = (final velocity - initial velocity) / time.
Why slowing down of an object is considered to be form of acceleration?
When an object slows down, its velocity decreases. Since acceleration is the rate of change of velocity, slowing down involves a negative acceleration. This is because the velocity is changing in the direction opposite to the initial motion.
How do you calculate an objects acceleration?
Acceleration is an object's change in velocity divided by its change in time. So: acceleration=(final velocity - initial velocity)/(final time - initial time)
How do you calcuclate the acceleration of a moving obect?
Acceleration can be calculated using the formula: acceleration = (final velocity - initial velocity) / time. Simply subtract the initial velocity from the final velocity, then divide by the time taken to change the velocity. The resulting value will be the acceleration of the moving object.
An object has initial velocity in the upward direction a final velocity in the downward direction and undergoes constant acceleration What can you say about its average acceleration?
The average acceleration of the object will be negative since it changes direction from upward to downward velocity. The acceleration will be constant because the object undergoes constant acceleration throughout the motion.
Differentiate positive acceleration and negative acceleration?
Positive acceleration occurs when an object's velocity is increasing over time, while negative acceleration occurs when an object's velocity is decreasing. Positive acceleration is associated with motion in the direction of velocity, while negative acceleration usually indicates motion in the opposite direction of velocity.
