1. The problem statement, all variables and given/known data An object is thrown with speed 20 m/Sunder the angle pi/3 rad with the horisontal direction. In the highest point, the object is divised into two pieces with same weights. One of them, after the division has the speed 0. How far from the starting point do the pieces fall on ground? 2. Relevant equations t=2v0sina/g 3. The attempt at a solution The piece that has the speed 0: x1=v0^2sin2a/2g=17.32 m x2=v0^2sin2a/g=34.64 m The answer in the book is 10, 20 meters.
