Question

Find the length of a pendulum that makes one swing in 3 s. The equation for the time of one swing of a pendulum is T= 2pi sqrt(L/32) , where T is the time in seconds and L is the length in feet. Round to the nearest hundredth.

Answer 1

Answer:

7.30

Step-by-step explanation:

T = 2π √(L/32)

3 = 2π √(L/32)

3/(2π) = √(L/32)

(3/(2π))² = L/32

L = 32 (3/(2π))²

L ≈ 7.30
