A car is traveling at 10 m/s. A.) How fast would the car need to travel to have 2.56 times kinetic energy? m/s

Since the investigative question has two variables, you need to focus on each one separately. thinking only about the first part of the question, mass, what might be a hypothesis that would illustrate the relationship between mass and kinetic energy? use the format of "if…then…because…” when writing your hypothesis.

Um vetor representa um deslocamento cujo módulo é 20 m. se v faz um ângulo de 60 graus com a horizontal, qual é o valor das componentes horizontal e vertical deste vetor?

You've already seen the value of 9.8 in this lesson. what's this value called? what quantity does it represent?
