A scouting party sets out to explore. The party's leader-a hysicist, naturally-immediately makes a determination of the acceleration due to gravity on the Pink lanet's surface by means of a simple pendulum of length 1.06 m. She sets the pendulum swinging. and her collaborators carefully count 109 complete cycles of oscillation during 217 s. What is the result Number m/s A Previous ® Give Up & View Solution Check Answer Next Ext O Hint

Explanation / Answer

Time period for 1 oscillation,
T = 217 s/ 109 cycle
    = 1.991 s

use:
T = 2*pi* sqrt (L/g)
1.991 = 2*pi*sqrt (1.06/g)
1.06/g = 0.1004
g = 10.6 m/s^2

Answer: 10.6 m/s^2
