A pendulum hangs from the ceiling, consists of a mass that is attached to a string with a length of 10 cm. The pendulum is set to motion with a vertical height of 2 cm from its lowest position. The pendulum moves from its initial release position to the lowest point takes about 0.8 seconds. A. Determine the period of the motion

B. Determine the equation of the motion, h=h(t), where the height is measured from the lowest point.

C. Determine the times within one cycle when the bob is 1 cm from the lowest point.

step-by-step explanation:

second option

step-by-step explanation:

the measures of a triangle equal 180. use that to find x.

2x+3x+4x=180

9x=180

9x/9=180/9

x=20

now you know x, you know angle a is 40°, angle b is 60°, angle c is 80°.

because angle a is 40°, the first option doesn't work.

because angle b is 60°, the second option does work.

when you add angle a and b, you get 100°. complementary means it equals 90°, so the third option doesn't work.

when you add angle a and c, you get 120°, which is not 100.

your answer is -9
