1. The problem statement, all variables and given/known data We push a weight hanging on a long string in a horizontal direction so that the velocity at the beginning is v = 10 cm / s. What is the oscillating time of such a pendulum, if the string on which hangs deviates the most for θ = 5 º? 2. Relevant equations T = 2pie[sqrt(L/g)] 3. The attempt at a solution Calculating the length of the string: v² = 2gL[1-cosθ] → L= v² / 2g[1-cosθ] L= 0.3 cm Calculating the oscillating time: T = 2pie[sqrt(L/g)] T= 0.35 s Are my calculations correct? Thank you for helping!
