A ball is launched at a speed of 10ms-1. It lands 5m away. Find the two possible values of the angle, θ, which the initial trajectory makes with the horizontal.
Homework Equations
The equations of motion.
The Attempt at a Solution
I realize that I need to find the angle θ and then use sin(180-θ) to find the other possible angle however I do not know how to get it.

A steep trajectory is a path or course that has a high slope or incline. In science, it is often used to describe the movement or flight of an object, such as a rocket or projectile, that has a sharp upward angle.
A shallow trajectory is a path or course that has a low slope or incline. In comparison to a steep trajectory, it has a gentler upward angle. This can also be seen in the movement or flight of an object, such as a plane or bird, where the angle of ascent is more gradual.
The steepness or shallowness of a trajectory is largely influenced by the initial velocity and the angle of launch. A higher initial velocity and a steeper angle of launch will result in a steeper trajectory, while a lower initial velocity and a shallower angle of launch will result in a shallower trajectory.
Steep and shallow trajectories are used in various fields of science, such as physics, astronomy, and engineering. They can be used to analyze the motion of objects, predict the flight paths of projectiles, and calculate the orbits of planets and satellites.
Some real-life examples of steep trajectories include the launch of a rocket into space, the flight of a ski jumper, and the path of a thrown baseball. Examples of shallow trajectories include the flight of a frisbee, the trajectory of a golf ball after being hit, and the movement of a paraglider.
