1. The problem statement, all variables and given/known data A ball is thrown horizontal out of a window 18m above the ground. it is thrown horizontally at 5.0ms. show that it takes about 2 seconds to drop. 2. Relevant equations S=ut+1/2at^2 3. The attempt at a solution u=0 a=9.8 s=18 18=0t+1/2*9.8t^2 36=9.8t^2 sqrt3.6734=t t=1.92 is this near enough too 2 to be the right answer or have i made a mistake some where i was not sure if the horizontal force would have any effect on the time taken to drop. Any help would be much appreciated.
