Please, I need help with this problem:
A ball is thrown at a velocity of 2 m/s and at an inclination of 60° with repsect to the ground. At the same time, a second ball is thrown from a height h greater than the first, with a speed of 2 m/s and an inclination with respect to the ground of 30°

determine for which values h the trajectories of the 2 balloons do not intersect

result: h>0,1 m

Thank you in advance
