a) Calculate the period of a ball tied to a string of length 0.7 m making 7.9 revolutions every second. Answer in units of s.

B) Calculate the speed of the ball. Answer in units of m/s.

Thank you for the opportunity to help you with your question!

he period of a ball in circular motion is 1/Frequency so 1/7.9 = 0.126 seconds. The speed is distance over time and the distance traveled in 1 second is: 7.9 revolutions times the circumference (pi*d)= 7.9*pi*2*0.7= 34.75 m/s
