Homework Statement
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?
Homework Equations
t=2v0sina/g
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.
