Закон сохранения импульса для внутреннего неупругого столкновения:
${m_{1} *v_{1}- m_{2} v_{2} = ({m_{1}+ m_{2} )*v$
(где v-скорость после столкновения.)
$v= frac{m_{1} *v_{1}- m_{2}* v_{2} }{m_{1}+ m_{2} }$
$v= frac{3*2-2*3}{2+3} = frac{6-6}{5} = frac{0}{5} =0$ м/с
ответ: 0 м/с

Charlie Chaplin was the first and the greatest movie star of all time. He was born in London in 1889 in the family of two music hall performers. His parents taught him to sing and dance, and by the age of seven he was already appearing regularly on the stage. At the age of twenty-four an American producer offered him a film contract. From the very beginning his films were successful, his popularity grew. In 1917 he was paid 1 million dollars for eight movies of 20 minutes without sound.

The absence of sound in the motion pictures of that period may have contributed to Chaplin’s popularity. Since he spoke no language on the screen, people from different countries could easily watch his films.

The most significant factor in Chaplin’s popularity was the character he portrayed on his films. The Little Fellow expressed the joy and sorrow, the dreams and frustrations that everyone experiences in life. Equally important was the fact that Chaplin expressed these things with humor and he made people laugh nearly every second. His best movies are City Lights, Modern Times and The Gold Rush.

Ironically, The Little Fellow was created quite by accident, when the director of the motion picture suggested that Chaplin come up with something that would make the movie funnier. “I thought I would dress in baggy pants, big shoes and derby hat,” Chaplin explained later in his autobiography. “I wanted everything a contradiction: the pant baggy, the coat tight, the hat small, the shoes large.” He wore comical false moustache and one of the most famous characters in his history of motion pictures was born — Charlie Chaplin as The Little Fellow.

Write true, false, doesn’t say:

1. There are many books about this actor.

2. The absence of sound in the motion pictures of that period may have contributed to Chaplin’s popularity.

3. The Little Fellow was created quite by accident.
