Answer:
200 seconds
Step-by-step explanation:
To calculate the time it will take for the ball to roll 160 meters at a speed of 0.8 m/s, we can use the formula:
Time = Distance / Speed
In this case, the distance is 160 meters and the speed is 0.8 m/s.
Substituting these values into the formula, we have:
Time = 160 meters / 0.8 m/s
Now, let's divide the distance by the speed to find the time:
Time = 200 seconds
Therefore, it will take the ball approximately 200 seconds to roll 160 meters at a speed of 0.8 m/s.
It's important to note that this calculation assumes that the speed remains constant throughout the entire distance. In reality, factors like friction and other external forces may affect the actual time it takes for the ball to roll the given distance.
