Which Object Has the Greater Instantaneous Velocity?

Click For Summary

Homework Help Overview

The discussion revolves around a velocity-time graph involving two objects, A and B. Object A maintains a constant velocity of 4 m/s, while object B starts at 8 m/s and decreases to 0 m/s over a 5-second interval. Participants are exploring the concept of instantaneous velocity and comparing the velocities of the two objects at a specific time.

Discussion Character

  • Exploratory, Conceptual clarification

Approaches and Questions Raised

  • Participants are attempting to clarify what is meant by instantaneous velocity and at what specific time it should be evaluated. There is a focus on comparing the instantaneous velocities of both objects at the 5-second mark.

Discussion Status

Some participants are actively seeking clarification on the specific time for evaluating instantaneous velocity, while others reiterate the need to determine the velocities of both objects at 5 seconds. The discussion is ongoing, with no consensus reached yet.

Contextual Notes

There is a mention of potential confusion regarding the problem setup, and participants are working within the constraints of the information provided in the velocity-time graph.

A velocity time graph starts from 0-5 s , object A has constant velocity of 4 m/s. Object B has an initial velocity of 8 m/s and constantly decreases and reaches 0 m/s at 5 s. so i need to know what is the instantaneous velocity. Also, which of the object's instantaneous velocity is greater. sorry if this is confusing.

Instantaneous velocity occurs at some specific time. What time are you being asked about?
 
it asks at time 5 which instantaneous velocity is greater

Okay, then what is the velocity of A at 5 s?
