calculate the period of a ball tied to a string of length 1.9 m making 1.5 revolutions every second
To calculate the period of a ball tied to a string, we need to know the frequency of its motion. The frequency represents the number of complete revolutions (or cycles) the ball makes in one second.
In this scenario, we are given that the ball makes 1.5 revolutions every second. To find the period, we can use the formula:
Period (T) = 1 / Frequency (f)
Given that the frequency is 1.5 revolutions per second, we can substitute it into the formula:
T = 1 / 1.5
To simplify the calculation, let's convert the fraction into a decimal:
T = 0.67 seconds
Therefore, the period of the ball is approximately 0.67 seconds.
