PLS HELP ILL MARK YOU BRAINIEST 3. A 57.0 kg diver dives from a height of 15.0 m. She reaches a speed of 14.0 m/s just
before entering the water. What was the average force of air resistance (e. g., friction)
acting on the diver?
Bonus: What is the force of friction underwater if she reaches a depth of 2.5 m before
stopping? Do not neglect the buoyant force of 500 N acting on the diver once underwater.

Answer asap! the weather patterns on earth are shown in this image. explain why there are convection currents; why there are hotter and colder parts of earth.

Ateam of astronauts is on a mission to land on and explore a large asteroid. in addition to collecting samples and performing experiments, one of their tasks is to demonstrate the concept of the escape speed by throwing rocks straight up at various initial speeds. with what minimum initial speed vesc will the rocks need to be thrown in order for them never to "fall" back to the asteroid? assume that the asteroid is approximately spherical, with an average density p 3.84 x108 g/m3 and volume v 2.17 x 1012 m3 recall that the universal gravitational constant is g 6.67 x 10-11 n m2/kg2
