Given a position function for an object, under which of these conditions is the object’s speed decreasing? (1 point)
Responses when the velocity is negative and decreasing
when the velocity is negative and decreasing
when the velocity is positive and increasing when the velocity is positive and increasing
when the velocity is negative and the acceleration is negative
when the velocity is negative and the acceleration is negative
when the velocity is negative and the acceleration is positive
when the velocity is negative and the acceleration is positive
when the velocity is negative and the acceleration is zero
The object's speed is decreasing when the velocity is negative and decreasing.
The object's speed is decreasing under the condition when the velocity is negative and the acceleration is positive.
To determine when the object's speed is decreasing, we need to analyze the relationship between velocity and acceleration.
Speed is the absolute value of velocity, so when the velocity is negative, it means the object is moving in the opposite direction of its positive reference point.
If the velocity is negative and decreasing, it means the object is slowing down while moving in the opposite direction. Therefore, this condition satisfies the requirement of the object's speed decreasing.
So, the correct response is: when the velocity is negative and decreasing.
