2. Un dispositivo móvil diseñado y construido por los alumnos de física es autopropulsado por la corriente de aire que sale de u

n globo inflado. Calcula la fuerza que impulsa hacia adelante al dispositivo si partiendo del reposo alcanza una velocidad de 3 m/s en un tiempo de 5 segundos. Calcula también la fuerza de reacción que ejerce el piso sobre las llantas del dispositivo si la masa de este es de 4 kilogramos. No consideres la fricción entre el piso y las llantas del dispositivo. Calcula nuevamente los valores anteriores si los alumnos deciden agregar al móvil un pasajero con masa igual a 0.5 kg y compara los resultados​

According to Newton's third law of motion, when air is pushed back out of the balloon (out of the end through the opening), there must be an equal and opposite reaction force pushing the balloon forward (the end opposite the opening). When you let a balloon go on its own, it tends to fly randomly around the room, and is nearly impossible to steer. However, when you attach the balloon to a car, you can harness the energy of the balloon to propel the car. The engineering objective in this project will be to design, build and test a car that it is powered by nothing but a balloon. You want to design your car so that it can travel the greatest distance as far as possible.

Explanation:

Je crois que je ne vais plus à l'école. Les professeurs expliquent les leçons mais je ne comprends rien. Je finis les cours et je rentre à la maison. Mes devoirs me donnent mal à la tête. Je ferme mes livres et je dors. Demain, je vais rester à la maison!

This will not take 30 seconds to say, but it includes at least 5 verbs. You didn't specify verb tense so I kept it in the present tense.

I need to write a possion de avril poem and barely have a grasp on the vocabulary. Just by turning something in I'll get a passi
Lady_Fox [76]

Answer: Le premier d'avril. Il fait beau!

Je rêve d'une promenade sur la plage.

On veut mettre un poisson sur le dos.

Méfiez-vous des poissons rouges. Soyez sage!

Explanation:

The traditional April Fool's prank in France is to pin/tape a red fish to someone's back without them noticing. People may start laughing at the "victim" of the prank. So, this "poem" is a commentary.

The first of April. The weather is nice!

I dream of taking a walk on the beach.

People want to put a fish on your back.

Beware of red fish. Be wise!

This will never pass as great literature, but it may help you pass.

(If I have used vocabulary you don't have in your glossary, be careful!)
