Hi, in this question it is given that if the acceleration of the object is negative, what happens to the object? that is, the object slows down, speeds up or may speed up or down depending upon the whether the velocity is positive or negative.
00:19
That is what we need to find it out.
00:21
We need to explain.
00:22
For clear -cut explanation, so let us take an example of a car moving with a velocity, initial velocity of 100 meters per second.
00:31
Let us say the car is moving with an initial velocity of 100 meters per second and final velocity of 60 meters per second.
00:45
Let us say this is for an example we are going to check it out whether it slows down or speeds up or it may speed up or slow down depending upon the velocity is positive or negative.
00:58
Let us find out the acceleration now.
01:01
So for this, let us use the speed.
01:02
The equation of motion to determine the acceleration.
01:06
So the equation of motion v is equal to u plus a t.
01:14
So from this we can write the acceleration a is equal to v minus u by the time duration time taken by the object or the core.
01:31
Now let us plug the given values and determine the acceleration of the object...
