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

AI Thread Summary
The discussion revolves around calculating the time it takes for a stone to reach the ground when falling from a building with an initial speed of 32 m/s, neglecting air resistance. Participants note that the lack of distance information makes the question ambiguous, as typically both distance and speed are needed for accurate calculations. One participant suggests that if 32 m/s is the speed upon impact, the flight time could be calculated as one second, with a distance of 16 meters. The importance of understanding the direction of motion is highlighted as crucial for solving the problem. Overall, the consensus is that the question lacks sufficient data for a definitive answer.

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.

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'.
 

Thread 'Errors and significant figures'

I multiplied the values first without the error limit. Got 19.38. rounded it off to 2 significant figures since the given data has 2 significant figures. So = 19. For error I used the above formula. It comes out about 1.48. Now my question is. Should I write the answer as 19±1.5 (rounding 1.48 to 2 significant figures) OR should I write it as 19±1. So in short, should the error have same number of significant figures as the mean value or should it have the same number of decimal places as...

Thread 'A cylinder connected to a hanging mass'

Let's declare that for the cylinder, mass = M = 10 kg Radius = R = 4 m For the wall and the floor, Friction coeff = ##\mu## = 0.5 For the hanging mass, mass = m = 11 kg First, we divide the force according to their respective plane (x and y thing, correct me if I'm wrong) and according to which, cylinder or the hanging mass, they're working on. Force on the hanging mass $$mg - T = ma$$ Force(Cylinder) on y $$N_f + f_w - Mg = 0$$ Force(Cylinder) on x $$T + f_f - N_w = Ma$$ There's also...
