there will be no noise with the ball
If the ball travels 19.6 meters every second and it travels for 3 seconds, obviously you have to multiply the velocity by 3:
19.6 x 3= 58.8m/s
A.
if you have seen a newton's cradle this will make sense.
in order for both of them to travel at the same speed, the balls need to have the same mass and the speed to begin with tocontinue to travel at the same speed because mass can affect the impact of the force on the balls by each other, causing each ball to have different speeds.
The (frequency of the wave multiplied by the number of seconds
in a given amount of time) is the measure of the number of waves that
pass a point in that amount of time.
If you had said "in one second" instead of "in a given amount of time,
then the word in the blank would simply be frequency.
