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 = 2.00 s when the acceleration due to gravity is 9.80 m/s2. Your design for the pendulum includes a small object of mass m1 = 2.16 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.
(a)Determine the required length L for the rod (in m) when the clock is operating with a 2.00 s period on Earth.
(b)As shown in (b) of the figure, when the clock is operated on Mars, a small object of mass m2 can be mounted at a position r 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 m2 while keeping m1 fixed in both mass and position. The acceleration due to gravity on Mars is 37.6% of that on Earth. Determine the design requirement for the mass m2 when the clock is operating with a 2.00 s period on Mars. (Entered the required mass in kg.)

- An ideal spring hangs from the ceiling. A 1.25 kg mass is hung from the spring, stretching the spring a distance d = 0.0865 m from its original length when it reaches equilibrium. The mass is then lifted up a distance L = 0.0325 m from the equilibrium position and released. What is the kinetic energy K of the mass at the instant it passes back through the equilibrium position? K = d Equilibrium position wwwwww. wwwarrow_forwardhow to do?arrow_forward108 mand 25,551 T&T 8. A grandfather clock uses a pendulum that is 76.0 cm long. It is accidentally broken, and when repaired the length is shorter by 2.60 mm.

- A small mass m is attached to a string of length L to make a simple pendulum that swings with period T. Suppose the mass is cut in half, what might the new period of oscillation be? Α. 2T T В. С.Т D. V2T An alien on Pluto has the exact same pendulum. What is the period of oscillation of the alien's pendulum in terms of T, given that the acceleration due to gravity on Pluto is 1/16 of the acceleration due to gravity on Earth? TPlutoarrow_forwardIn the past, the fact that a simple pendulum has a constant period has been used as the basic timing mechanism for clocks. As a matter of fact, an old "Grandfather Clock" did use the swing of its pendulum to generate the ticks of the clock. Suppose you wanted a pendulum to have a period of 2.50 seconds, how long would it have to be (calculate to 3 significant digits).arrow_forwardConsider an ideal spring with spring constant k = 20 N/m. The spring is attached to an object of mass m = 2.0 kg that lies on a horizontal frictionless surface. The spring-mass system is compressed a distance xo = 50 cm from equilibrium and then released with an initial speed vo= 0 m/s toward the equilibrium position. x=0 equilibrium initial state a. What is the period of oscillation for this system? b. Starting at t = 0, how long will it take for the object to first return to the equilibrium position?arrow_forward
