The discussion revolves around a problem in kinematics, specifically focusing on the change in direction of velocity and its relation to acceleration. The original poster describes a scenario where a car changes its direction of motion while maintaining a constant speed.
The conversation includes attempts to clarify the calculation of average acceleration and the direction of that acceleration in relation to the change in velocity. Some participants provide guidance on ensuring proper units are attached to the calculations. There is an acknowledgment of the need to be cautious when applying kinematic formulas.
Participants note the time involved in the change of direction, which is specified as 2 seconds. There is also a mention of the potential complexity of using kinematic formulas in this context.
Looks good. But don't forget to attach the appropriate units.ahmed emad said:A=∆v/t so 5✓2 /2 , is that right?
Yes, the direction of the average acceleration will be in the direction of Δv.ahmed emad said:But is the direction of acceleraion will be the direction of ∆v?
What did you have in mind? Is there more to this problem? (Be careful not to apply formulas meant for 1D motion with constant acceleration.)ahmed emad said:And can I use kinimaticts fourmlas with this acceleration?
