1.) Explain the path of the rocket? When is it speeding up (accelerating), slowing down (- acceleration)? How do you think you might determine the distance that a model rocket would go into the air?

//Entry 1: This diagram displays the flight path of a rocket (see Figure 1). Each dot on the chart shows a point in time. As shown in Figure 1 the speed of the rocket decreases on the way up, and increases on the way down as time passes. Yet on the flight up the velocity is positive but on the flight down the velocity is a negative number. Velocity is the same thing as speed yet velocity determines a direction. This may be why the velocity is negative meaning that it is going in an oppisite direction. Instead of going up the rocket is going down. Once the rocket starts to go down it means that it has reached the top of its parabola and is starting its flight downward back towards earth. I think that a rocket would go farther with an engine that burns out in more than 3 seconds if the engine had burned out in 5 seconds the flight would have been higher. The engine starts burning out on the chart when speed and velocity begin to decrease. I think you could determine how high a rocket goes up by the upward flight time and the upward force (speed) you may be able to find how high a rocket would go with these two facts.//
