3- Plane bombarding a target
A plane fles horizontally at an altitude h = 4 km with a horizontal speed
of 540 km/h; it launches, without speed relative to the plane, a bomb. The
pilot intends to bombard an immobile target, ahead on the ground.
To study the motion of the bomb, we consider the system (xOy) of origin O
representing the position of the plane at the instant of launching of the bomb
as shown in the adjacent figure. We neglect air resistance. Given g = 9.8
m/s.
