¿puede cambiar el sentido de la velocidad de un objeto cuando tiene la aceleracion constante?

Okay so i'm taking an online spanish course (penn foster), and in the study guide, you have to create a bunch of sentences with words you've learned so far. translating, reading, and those kinds of things are fairly easy, but when it comes to making my own sentences, my brain just kinda waltz's away. anyone got any tips?

14. choose the answer that best completes the sentence. (practicar) fútbol. (2 points) a: practica b: practicamos c: practico d: practicáis

Which verb form correctly completes this sentence? mis amigos me ir al museo. a. sugerí b. sugeriste c. sugirieron d. sugerimos
