A sperm whale can dive to a depth of 3 km in 1 hour 52 minutes Can a swimmer-operator take a movie if his maximum diving speed is 50 cm / s?
These tasks: H (the depth to which the sperm whale can dive) = 3 km (in SI H = 3000 m); t (duration of immersion of the sperm whale) = 1 h 52 min (in SI t = 6720 s); V2 (maximum immersion speed of the swimmer-operator) = 50 cm / s (in SI V2 = 0.5 m / s).
1) Determine the speed of diving to the depth of the sperm whale: V1 = H / t = 3000/6720 = 0.446 m / s.
2) Comparison of speeds: V1 (0.446 m / s) <V2 (0.5 m / s), therefore, at the maximum diving speed, the swimmer-operator will be able to take pictures.
One of the components of a person's success in our time is receiving modern high-quality education, mastering the knowledge, skills and abilities necessary for life in society. A person today needs to study almost all his life, mastering everything new and new, acquiring the necessary professional qualities.
