Answer 1

80см=0,8м V=s/t V= 0,8м/2сек=0,4м/сек

Answer 2

How to Determine the Speed of a Ball?

To determine the speed of a ball, you need to know the distance the ball traveled and the time it took to cover that distance. In your case, the ball traveled a distance of 80 cm in a time of 2 seconds.

To calculate the speed of the ball, you can use the formula:

Speed = Distance / Time

Substituting the given values, we have:

Speed = 80 cm / 2 sec

Now, let's convert the units to a more commonly used measurement, such as meters per second (m/s). Since 1 meter is equal to 100 centimeters, we can convert the distance as follows:

Speed = (80 cm / 100) m / 2 sec

Simplifying the equation:

Speed = 0.8 m / 2 sec

Finally, calculating the speed:

Speed = 0.4 m/s

Therefore, the speed of the ball is 0.4 meters per second.

Please note that this calculation assumes a constant speed throughout the entire duration of the ball's travel. If the speed of the ball varied during its journey, this calculation would provide an average speed.
