## Homework Statement

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 realise 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.
