Дано:
m=1кг
V₁=2м/с
V₂=5м/с
t=1,5с
F-?
По 2 закону Ньютона F=ma, a= $frac{V _{2}- V_{1} }{t}$
a= $frac{5-2}{1,5}=2$
a=2м/с²
F=1кг*2м/с²=2Н

Answer the following questions. Type in no more than two words.

The world's largest charitable organizations used to be concentrated mostly in the United States. It was before the development of the European Foundation Centre, which currently unites more than 400 of the largest charitable foundations in Europe.

The Stichting INGKA Foundation

The fund is $ 36 billion, and it is currently the largest charitable organization in the world. The founder and owner of IKEA, a Swedish businessman Ingvar Kamprad created it.

The Foundation was established in 1982primarily to support modern solutions and the development of the architecture and interior design industry. At the same time, a significant part of the Fund's assets is spent not on charity, but investment projects. The amount of charitable assistance is about $ 10 million annually.

The Bill & Melinda Gates Foundation

The Fund's assets amount to more than $ 33 billion. Microsoft owner Bill Gates together with his wife and father founded the organization. Although the date of creation is relatively recent in 1994, the organization almost immediately outstripped the oldest charitable foundations in the world in terms of the amount of capital invested in charity.

The Fund supports primarily the poor, to finance the search for new methods to treat serious diseases, and to support programmes in the field of health and education. The Foundation spends almost $ 2 billion on charity every year.

The Wellcome Trust

The fund is more than $ 22 billion. The London charity organization was founded in 1936 and dedicated to the memory of Henry Wellcome, a pharmaceutical magnate. The main purpose of the Fund is to finance research activities aimed at protecting the lives of people and animals.

This Foundation has practically put charity on a professional basis in Europe, becoming the largest and most authoritative. The organization offers a large number of grants for scientific research and educational programmes for medical professionals.

These are not all charitable foundations in the world that donate billions of dollars to social causes. It is worth mentioning the United Way Worldwide charitable Foundation. The organization has offices in 46 countries and has a budget of more than $ 5 billion.
