To find the force of the swing as it bottoms out, I used the pendulum force equation, F = mg sinθ. We were able to find the starting angle with tools such as a protractor and proportioned diagrams of the swing. We used our average weight, 150 pounds, or 70.3 kilograms, as the mass. After solving, the force at the bottom of the swing was found to be about 344.5 Newtons.
To find the velocity forward, we used footage of one of us using the swing from the highest point. Using a combination of conversions and the velocity formula, V=d/t, we were able to find that the highest velocity that the swing reached was about 1.524 meters per second
