3. Four friends, Rashmi, Bryn, Tristin, and U'ilani, prepare to embark on a hot air balloon ride. A guide accompanies them during their ride and operates the balloon for their safety. Just before the guide releases the tethering ropes, while they are in static equilibrium, the balloon experiences a lift force (pushing up) and a crosswind (pushing sideways). The figure provides the weights of the balloon and each person in the basket and the magnitudes of the lift and wind forces acting on the balloon. Calculate the magnitudes of the tension forces in each tethering rope (AB, AC, and AD) at this instant. You can model the hot air balloon and all five people as a single particle at point A.
