Charles Lindbergh’s achievement
On 20th May 1927 a small fixed-wing singleengined aeroplane loaded with its maximum capacity of fuel (450 gallons) struggled to get airborne as it bounced down the runway at Roosevelt Field, New York. To avoid extra weight, the parachute, the radio and even the brakes had been removed by themechanic. At last it lifted off, just avoiding some telephone wires, and disappeared into the distance.
Thirty hours later a hundred thousand Parisians lined up at the Le Bourget Airport to wait for the arrival of the plane. It was 10 o’clock at night. Burning lanterns marked out the runway. Then came the low-pitched sound of an engine and a wave of excitement swept through the crowd. The Spirit of St. Louis touched down and rolled to the end of the runway. Out of the plane stepped a tall handsome American – Charles Lindbergh. He’d just become the first person to fly solo across the Atlantic, and he was destined to become one of the most famous men in the world.

Uma partícula A é lançada de um ponto O no solo, segundo um ângulo de 30º com a horizontal e velocidade inicial de 100 m/s. Instantes depois, uma outra partícula B é lançada do mesmo ponto O, com a mesma velocidade inicial de 100 m/s, porém, agora com um ângulo de 45º com a horizontal. Considerando o módulo da aceleração da gravidade igual a 10 m/s² e desprezando a resistência do ar, determine a diferença, em m, entre as alturas máximas, estabelecidas em relação ao solo, alcançadas pelas partículas.
Dado: !$ { \large \sqrt{2} \over 2} = 0,7 !$

Smart traveler, expert opinion about the airport
The first piece of advice is, people should always carry a good book. It helps to pass the time as you wait for your delayed flight. Don’t forget to take a sweater or a jacket on the plane. It can get very cold on a long night flight. And then there is airline food. Take a snack (cookies or fruit) with you. Sometimes the food is late, sometimes it doesn’t arrive at all, andit’s never very good.

Em um Laboratório de Física o aluno dispunha de uma régua, uma mola e dois blocos. Um bloco com massa igual a 10 kg, que o aluno denominou de bloco A e outro de valor desconhecido, que denominou bloco B. Ele montou o experimento de forma que prendeu o bloco A na mola e reparou que a mola sofreu uma distenção de 5 cm. Retirou o bloco A e ao colocar o bloco B percebeu que a mola distendeu 7,5 cm. Com base nestas informações, e admitindo a mola ideal e a aceleração da gravidade igual a 10 m/s², o aluno concluiu corretamente que o bloco B tem massa igual a ______ kg.
Observação: mola ideal é aquela que obedece a Lei de Hooke.
