Скорость -производная от координат, в проекциях на оси
Vx=6t², Vy=9t², Vx(5)=150 , Vy(5)= 225, модуль векторной суммы V= √(Vx²+Vy²)=270.4 м/с

38. Read and match the texts with headings. A Can't animals just run away from a fire? B Were the Australia fires caused by climate change? C What about the future? D How big were the Australia fires 2020? E How do the Australia fires usually start? F How many animals have died in the fires? 1) Bushfires have always been a part of Australia's ecology and environment for thousands of years. Fires are usually caused by a thunderstorm. But some fires are started by people. The worst fires are caused by a long period when there is no rain and there are heat waves. The bushfires of 2019-2020 were a lot worse than normal. At least 26 people died. 2) More than 63,000 sq km in Victoria state, the Blue Mountains, the regions in Southern and Western Australia were on fire. This territory is as big as 6.3 million sports fields. An environmental scientist of the WWW Australia, Stuart Blanch, said that the fires had reached Victoria's Alpine National Park and New South Wales's Kosciuszko National Park – home to very rare animals. 3) Scientists have long talked that the climate is changing. Hotter and drier weather makes the risk of fires. In September 2019, the weather in Australia was too hot and dry. In January, the Australia's driest summer month, rainfall was 40% lower than average. It was caused by rising levels of CO2 on the planet. Australia had a new temperature record: an average maximum of 41.9C was recorded on 18 December 2019. 4) More than 1,250,000,000 animals have died in Australia's wildfires. This includes thousands of koalas, kangaroos, wallabies, kookaburras, cockatoos and honeyeaters which were burnt alive. But the fires don't only kill animals, they also ruined their habitat, leaving the animals without food and home.
