If you only have the initial velocity (v₀) and the time (t) of the object thrown, you can't determine the launch angle directly. However, based on this information, you can calculate the horizontal and vertical components of the initial velocity (if both components are provided), then find the angle with trigonometry. Here's how to proceed if you have both horizontal and vertical components of the initial velocity: 1. Calculate the horizontal component (v₀x) and vertical component (v₀y) of the initial velocity. 2. Use the arctangent function (tan^(-1)) to determine the angle (θ) from the horizontal and vertical components. θ = tan^(-1)(v₀y / v₀x) Make sure to convert the angle from radians to degrees if needed (multiply by (180/π)). If you don't have both horizontal and vertical components of the initial velocity, you'll need more information to determine the launch angle, such as maximum height or horizontal distance traveled.
