1. The problem statement, all variables and given/known data A pendulum swings at 70 cycles per minute. a. What is the frequency in Hz? b. What is the period in seconds? 2. Relevant equations T = 1 / f 3. The attempt at a solution For part a) Used the answer for part b & I took the equation above, divided 1 by 1.167 cycles/second & got 0.85 Hz For part b) What I did was divide 70 cycles by 60 seconds to get 1.167 cycles/second I feel like I did it correct but I had gotten it wrong when the teacher had graded my work.
