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.

If an object is accelerating what equation relates the acceleration of that object the initial velocity and the final velocity and time?
Vf = Vi + at Where Vf = final velocity Vi = initial velocity a = acceleration t = time
Can an object's acceleration be a negative number?
Yes it can be.When a body has its initial velocity greater than its final velocity, then the body can have negative acceleration since acc.=change in velocity/time
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)
If an object is accelerating what equation relates the distance traveled by that object to the initial velocity final velocity and time?
Final velocity = Initial velocity +(acceleration * time)
What is the definition of negative velocity?
Observe that the object below moves in the negativedirection with a changing velocity. An object which moves in the negative direction has a negative velocity. If the object is speeding up then its acceleration vector is directed in the same direction as its motion (in this case, a negative acceleration).
Formula in getting the acceleration of a moving object?
final velocity-initial velocity --------------------------------- time
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).
What is the velocity of an object that starts at 45 mph and accelerates at a rate of -10 mphsec for 3 seconds?
the final velocity = initial velocity + acceleration x time; since acceleration is negative final velocity = 45 - 10x3 = 45 -30 = 15 mph
Do Both speed and acceleration include the direction of an object's motion?
No. The velocity of an object is how fast it is moving as well as the direction of the motion. So when considering one dimension, the velocity can be positive or negative. The speed of the object is simply the magnitude (absolute value, in the case of one dimension) of the velocity, with no direction. Acceleration is the change in velocity and does include direction. So if an object has a positive velocity (in one dimension) and its speed increases, the acceleration is negative. However, if the speed of an object moving the negative direction increases, then the acceleration is negative, because the velocity becomes "more negative."
