THow high is the building if the time it takes for a lead weight dropped from the top of the building to fall the last 1.5 m before hitting the ground is 109s?
For the last 1.5m:s = ut + (1/2)at21.5 = ut + (1/2)*10*(109)21.5 - (1/2)*10*(109)2 = u * 109u = -545 ms-1It seems that for this situation to even exist, the lead weight must start going upwards from 1.5m at a speed greater than the speed of sound. This cannot happen if it's dropped off a building, obviously.For the situation to be believable, the time would have to be much shorter, or the distance much larger.
