- Constant Speed and Velocity:
When both the speed and velocity of the comet remain constant during a specific time interval, it suggests that the comet is moving in a straight line with uniform motion. In this case, "speed" refers to the magnitude of the comet's velocity, and "velocity" includes both the magnitude (speed) and direction of motion. The fact that both speed and velocity remain constant indicates that the comet is maintaining a consistent rate of motion in a specific direction without changing its speed or changing its direction.
2. Distance Travelled:
To determine the distance traveled during the period t = 0 s to t = 6.0 s, we can use the formula for distance traveled by an object with constant velocity:
Distance = Velocity × Time
Since the velocity is constant, we can use either the speed or the velocity value. Let's assume the value is v (speed or velocity):
Distance = v × (t = 6.0 s - t = 0 s)
Distance = v × 6.0 s
The distance traveled is directly proportional to the velocity and the time interval. If you have the value of the speed or velocity, you can substitute it into the equation to find the distance. If you don't have the value of the speed or velocity, you'll need that information to calculate the distance accurately.
