3. A 50.0kg diver jumps from a ledge 8.0m above a swimming pool and comes to rest 2.0m below the surface of the water. How fast is she going before she hits the water? What is the average force of water resistance that brings her to stop. If the energy of her dive goes into heating the water which has a volume of 2.5m ^ 3 how much warmer will the water become? The specific heat of water is 4186 J/(kg.^ C)Hey

Aboat radioed a distress call to a coast guard station. at the time of the call, a vector a from the station to the boat had a magnitude of 45.0 km and was directed 15.0° east of north. a vector from the station to the point where the boat was later found is = 30.0 km, 15.0° north of east. what are the components of the vector from the point where the distress call was made to point where the boat was found? in other words, what are the components of vector c = b - a?
