Circular Motion - $100 A clay ball is travelling in a vertical circle at the end of a string as shown below. If string is cut at point X, which direction will the clay ball go? Back to Board
Circular Motion- $200 A carousel initially at rest begins to accelerate constantly until it has reached an angular velocity ω after 2 complete revolutions. What is the angular acceleration of the carousel during this time in terms of ω and pi? Back to Board
Circular Motion - $300 A magician places a 5 kg rabbit in a lightweight hat and swings the hat in a vertical circle of radius 0. 6 meters. What is the minimum tangential speed needed so the rabbit doesn’t fall out? Back to Board
Circular Motion - $400 DAILY DOUBLE!!! Back to Board
Circular Motion - $500 A rigid bar with mass M and length L is free to rotate about a frictionless hinge. What is the angular acceleration of the bar immediately after it’s released at the horizontal position in terms of g and L? Hint: FG acts on the center of mass (L/2) I = 1/3 ML 2 Back to Board
Space/Gravity - $100 If F 1 is the magnitude of the force exerted by the Earth on a satellite in orbit about the Earth and F 2 is the magnitude of the force exerted by the satellite on the Earth, is F 1 greater than, less than, or equal to F 2? Back to Board
Space/Gravity $200 A satellite travels around the Sun in an elliptical orbit as shown above. As the satellite travels from point X to point Y, explain what happens to its speed angular momentum. (increases, decreases, remains the same) Back to Board
Space/Gravity $300 A newly discovered planet has twice the mass of the Earth, but the acceleration due to gravity on the new planet's surface is exactly the same as the acceleration due to gravity on the Earth's surface. The radius of the new planet in terms of the radius R of Earth is: Back to Board
Space/Gravity $400 Two artificial satellites I and II have circular orbits of radii R and 2 R, respectively, about the same planet. The orbital velocity of satellite I is v. What is the orbital velocity of satellite II in terms of v? Back to Board
Space/Gravity $500 A satellite S is in an elliptical orbit around a planet P, as shown above, with r 1 and r 2 being its closest and farthest distances, respectively, from the center of the planet. If the satellite has a speed v 1 at its closest distance, what is its speed at its farthest distance in terms of r 1, r 2, and v? Back to Board
Waves/Sound $100 Which harmonics are possible in a tube closed at one end? Back to Board
Waves/Sound $200 Dog whistles have frequency of 3. 0 x 104 Hz, much higher than humans can hear. What is the wavelength of these waves? Assume speed of sound = 340 m/s Back to Board
Waves/Sound $300 What is the standard unit for spring constant?
Waves/Sound $400 What is the frequency of the first overtone in the 1. 5 m long Ruben’s tube? Treat the tube as a tube open at both ends. Speed of sound in tube = 490 m/s Back to Board
Waves/Sound $500 Tanya talks long distance with her bae every night from a pay phone. She is limited to 10 min, so to measure the time, she swings the cord as she talks on the phone. If the cord is 0. 800 m long, how many complete swings will the phone receiver make before she must hang up? Back to Board
Definitions - $100 ____ is conserved if there is no net torque applied to the system. Back to Board
Definitions - $200 How circular or elliptical an ellipse is Back to Board
Definitions - $300 When the frequency of a forced vibration equals the natural frequency of an object Back to Board
Definitions - $400 A force that tries to return an object to equilibrium Back to Board
Definitions - $500 An exoplanet detection method that observes the bending of light around a planet’s gravity well Back to Board
Applications - $100 When a plane is moving faster than the speed of sound, the interference of the sound waves at the edge of the cone to the right produces a phenomenon called: Back to Board
Applications - $200 A certain star, of mass m and radius r, is rotating with an angular speed ω. After the star collapses, it has the same mass but with a much smaller radius. Describe its angular momentum, angular speed, and rotational inertia after it collapses. Back to Board
Applications $300 A sliding box, rolling hollow cylinder, and rolling solid cylinder are in a race down a frictionless ramp. Rank them in order from winner to loser. Back to Board
Applications - $400 What is the altitude (above the surface) of a geosynchronous satellite orbiting Earth? (1 day = 86400 seconds, MEarth = 5. 98 x 1024 kg, Rearth = 6. 38 x 106 m) Back to Board
Applications - $500 Redshift was used to show that the universe is expanding. How fast must a supernova be moving away from us in order to get a change in wavelength of 10 nm(i. e. from 650 x 10 -9 m to 660 x 10 -9 m)? (C= 3. 0 x 108 m/s) Back to Board
Random Facts $100 How old was Stephen Hawking? Back to Board
