That is asked is if acceleration is negative what of the following statement is correct if acceleration is negative option is given that if object's acceleration is in positive direction as its velocity that means we will draw the axis if this is an object if direction of velocity is in this direction and this is the direction of acceleration.
00:35
In this case, acceleration is negative.
00:41
So this is the correct option.
00:43
In next option, it is given that in coordinate system, upward acceleration is considered as a negative one.
00:50
So this is wrong.
00:52
And in a positive acceleration, so this is wrong.
00:56
And in downward direction, we consider the acceleration as a positive one.
01:02
So this is also wrong because in a positive direction.
01:05
In the upper direction, we consider it as positive acceleration and in downward direction, we consider it as negative acceleration.
01:12
And in these two statements, it is given as an opposite statement.
01:15
So both of those statements are wrong and acceleration is negative in case of opposite direction with velocity.
01:25
Opposite direction with velocity.
01:33
In next part of the question, velocity is given as 15 meter per second and time taken...
