Answer #1

given

length l = 6.3 m

from the realtion

time periode T = 2\pi \sqrt{l/g}

T = 2*3.14*sqrt(6.3/9.8) = 5.035 s

answer is 5.0 s

    (1 point) Suppose a pendulum with length L (meters) has angle 0 (radians) from the vertical. It can be shown that 0 as a function of time satisfies the differential equation: d20 + -sin 0 = 0 dt2 L where g = 9.8 m/sec/sec is the acceleration due to gravity. For small values of 0 we can use the approximation sin(0) ~ 0, and with that substitution, the differential equation becomes linear A. Determine the equation of motion of a...
