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

[nikkkk]

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'.
