How Far Will You Travel Before Hitting the Mosquito?

AI Thread Summary
The discussion revolves around a physics problem involving a mosquito flying toward a person and calculating displacement and time to collision. The mosquito has a velocity of 2.2 km/h east, while the person is moving toward it at 1.9 m/s, starting from a distance of 21.0 m. The equations of motion are referenced to determine the displacement and time to reach the mosquito. Participants confirm the calculations and express gratitude for assistance, indicating that the initial answers align with expectations. The conversation highlights the importance of verifying calculations in physics problems.

Homework Statement



A mosquito flies toward you with a velocity of 2.2 km/h (E). If you are traveling toward the mosquito with a speed of 1.9 m/s, and a distance of 21.0 m separates you and the mosquito initially:

A) What will your displacement be when you hit the mosquito? (7)

B) How long will it take you to reach the mosquito? (2)

*I checked my answers with the check digits (7) and (2) and it did not equal 5.

Homework Equations



Dyou : Dyou(initial) + Vyou(initial)t + (1/2)(ayou^2)(t^2)

Dmos : Dmos(initial) + Vmos(initial)t + (1/2)(amos^2)(t^2)

Yes, yours makes sense. I think this means that I've done the question correctly...

Thank you so much!
 
Thread 'Collision of a bullet on a rod-string system: query'
In this question, I have a question. I am NOT trying to solve it, but it is just a conceptual question. Consider the point on the rod, which connects the string and the rod. My question: just before and after the collision, is ANGULAR momentum CONSERVED about this point? Lets call the point which connects the string and rod as P. Why am I asking this? : it is clear from the scenario that the point of concern, which connects the string and the rod, moves in a circular path due to the string...
