To determine which two values would likely be equal for the object during the times marked by segments B and E in the given velocity versus time graph, we need to analyze the characteristics of each segment.
-
Segment B: This segment represents a downward slope from a positive velocity to zero velocity, indicating that the object is decelerating. The acceleration in this segment is negative (deceleration), meaning that the object is slowing down.
-
Segment E: In this segment, the graph is horizontal, indicating that the object's velocity is constant (at zero). Consequently, the acceleration in this segment is zero because there is no change in velocity.
Now, considering the options:
-
Mass: This is a constant characteristic of the object and does not change regardless of the velocity or time.
-
Net Force: According to Newton’s second law, if the acceleration is zero (like in segment E), the net force is also zero. However, in segment B, there is a deceleration (negative acceleration) involved, which means the net force would not be zero.
-
Acceleration: In segment B, there is a negative acceleration (deceleration), and in segment E, the acceleration is zero. These would not be equal.
-
Velocity: In segment B, the velocity is decreasing, and at a certain point, it reaches zero. In segment E, the velocity is constant and equal to zero.
Given this analysis, the two values that would likely be equal during segments B and E are the mass of the object. Mass remains constant whether the object is accelerating or moving at constant velocity.
Thus, the answer is: mass
