Question 4: PHYS 101
Consider a simple pendulum in which a point object of mass m = 4.00 kg is suspended from a string such that the pendulum length is L = 1.40 m. The period of the pendulum on an unknown planet is measured to be 5.00 s.
What is the gravitational constant on the planet?
(a) gplanet = 0.89 m/s2
b) gplanet = 0.06 m/s2
(c) gplanet = 35.00 m/s2
(d) gplanet = 1.76 m/s2
(e) gplanet = 2.21 m/s2
Now suppose the pendulum is mounted on the ceiling of an elevator on the planet. In which case is the period of the pendulum smaller than 5.00 s?
(a) The elevator is accelerating upward.
(b) The elevator is accelerating downward.
(c) None of these options.
