Calculating the time of an falling object provding with only speed.

Click For Summary

Homework Help Overview

The problem involves calculating the time it takes for a stone to fall from a building, given its initial speed of 32 m/s and neglecting air resistance. The context is related to kinematics and the effects of gravity on falling objects.

Discussion Character

  • Exploratory, Assumption checking

Approaches and Questions Raised

  • Participants discuss the importance of understanding the direction of motion and question the ambiguity of the problem. Some raise concerns about the lack of information regarding the distance the stone falls.

Discussion Status

The discussion is ongoing, with participants exploring different interpretations of the problem. Some suggest that the initial speed might be the speed at impact, while others express uncertainty about the adequacy of the provided information.

Contextual Notes

There is a mention of the stone's weight and mass, but participants note that the distance of the fall is not provided, leading to questions about how to proceed with the calculation.

Question: A stone is falling from the top of a buliding with 32m/s.
Air resistance is so small that it can be neglected.
the weight of the stone is 24N.
Calculate the time in second which the stone takes to reache the ground.
 
Physics news on Phys.org
Think about the direction of the motion. This is key in solving the problem as it provides you with more data.
 
so
Gravity=9.8N
Weight of stone=24N
Mass of stone=2.449

wouldnt i need the data of how long the distance is also?
 
seems to me as posted, the question is ambiguous and has no answer. Sure there isn't more?
 
Nope it was one of the questions in my exam
 
Not enough info as I read it which states that the object is falling with an iniitial v of 32/s. The only hope is to assume that 32'/s is the speed at which it strikes the ground. If so, its trivial. Flight time is one second, and distance is 16'.
