A lifeguard watches a swimmer train while sitting at their chair, fixed at point O. They swim at $$v = {{params.v}}$$ m/s, while they slow them at a rate of $${{params.a}}$$ m/s^2$$in the moment shown. Determine the following values where$$r$$is the length between the lifeguard and swimmer,$$h = $$m and$$x = \$ m.
