Calculate the period of a ball tied to a string of length 0.7 m making 7.9 revolutions every
Answer in units of s.
Thank you for the opportunity to help you with your question!
The period of a ball in circular motion is 1/Frequency so 1/7.9=0.1266 seconds
The speed is distance over time and the distance traveled in 1 second is:
u multiply the number of revolutions per second with the circumference of the circle to find speed (m/s)* circumfrenc2(0.7m)(3.14)e of circle = (2r)(pi)
speed of the ball: 4,396 * 7.9 =34.7284m/s
