You are working on the plans for an expedition to colonize Mars. In an effort to provide a homey atmosphere for the Mars colonists, the plan is to send a number of grandfather clocks along with the expedition. Each colonist apartment will contain one grandfather clock. You are in charge of designing the clock pendula. The clocks will have a pendulum with a period of T= 2.00s when the acceleration due to gravity is 9.80 m/s². Your design for the pendulum includes a small object of mass m, 2.39 kg mounted such that its center is at the end of a very light rod, as shown in (a) of the figure. The pivot point is at the upper end of the rod. CM (b) CMX @ (a) Determine the required length L for the rod (in m) when the clock is operating with a 2.00 s period on Earth. m (b) As shown in (b) of the figure, when the clock is operated on Mars, a small object of mass m, can be mounted at a position that is 31.5% of the length of the rod from its pivot point. This additional object allows the period of the pendulum to be adjusted when located in different gravitational fields by altering m, while keeping m, fixed in both mass and position. The acceleration due to gravity on Mars is 37.6% that on Earth. Determine the design requirement for the mass m₂ when the clock is operating with a 2.00 s period on Mars.
