Chapter 14, Problem 14.8DQ
You are captured by Martians, taken into their ship, and put to sleep. You awake some time later and find yourself locked in a small room with no windows. All the Martians have left you with is your digital watch, your school ring, and your long silver-chain necklace. Explain how you can determine whether you are still on earth or have been transported to Mars.

A possible means of space flight is to place a perfectly reflecting aluminized sheet into orbit around the Earth and then use the light from the Sun to push this "solar sail." Suppose a sail of area A = 5.20 ✕ 105 m2 and mass m = 6,800 kg is placed in orbit facing the Sun. Ignore all gravitational effects and assume a solar intensity of 1,370 W/m2.
(a)
What force (in N) is exerted on the sail? (Enter the magnitude.)
N
(b)
What is the sail's acceleration? (Enter the magnitude in µm/s2.)
µm/s2
(c)
Assuming the acceleration calculated in part (b) remains constant, find the time interval (in days) required for the sail to reach the Moon, 3.84 ✕ 108 m away, starting from rest at the Earth.
days
(d)
What If? If the solar sail were initially in Earth orbit at an altitude of 300 km, show that a sail of this mass density could not escape Earth's gravitational pull regardless of size. (Calculate the magnitude of the gravitational field in m/s2.)

- As the captain of the scientific team sent to Planet Physics, one of your tasks is to measure g�. You have a long, thin wire labeled 1.54 g/mg/m and a 1.24 kgkg weight. You have your accurate space cadet chronometer but, unfortunately, you seem to have forgotten a meter stick. Undeterred, you first find the midpoint of the wire by folding it in half. You then attach one end of the wire to the wall of your laboratory, stretch it horizontally to pass over a pulley at the midpoint of the wire, then tie the 1.24 kgkg weight to the end hanging over the pulley. By vibrating the wire, and measuring time with your chronometer, you find that the wire's second harmonic frequency is 200 HzHz. Next, with the 1.24 kgkg weight still tied to one end of the wire, you attach the other end to the ceiling to make a pendulum. You find that the pendulum requires 316 ss to complete 200 oscillations. Pulling out your trusty calculator, you get to work.What value of g will you report back to…arrow_forwardYou find a spring and feel compelled to hang it from a hook.

- m A large pendulum with a 200-lb goldplated bob 12 inches in diameter is on display in the lobby of theUnited Nations building. The pendulum has a length of 75 ft. It isused to show the rotation of the Earth—for this reason it is referredto as a Foucault pendulum. What is the least amount of time it takesfor the bob to swing from a position of maximum displacement tothe equilibrium position of the pendulum?
