A 114g puck is traveling at an initial speed of 6.7m/s and stops in 18 m due to friction of the ice. What is the magnitude of the friction force? What is the coefficeint of kinetic friction between
In a carnival booth, you win a stuffed giraffe if you toss a quarter into a small dish. The dish is on a shelf above the point where the quarter leaves your hand and is a horizontal distance of 2.1
Explain the process of charging by induction. Compare this to the process of charging an object by direct contact.
You are hanging on to the edge of a merry-go-round, and must exert a force of 100 N to hang on. If the speed of the merry-go-round doubles, how much force will you need to exert to hang on?
A ceiling fan with 89--diameter blades is turning at 65. Suppose the fan coasts to a stop 30 after being turned off. Through how many revolutions does the fan turn while stopping?
A woman rides a carnival Ferris wheel at radius 17 m, completing 4.3 turns about its horizontal axis every minute. What are (a) the period of the motion, and the magnitude of her centripetal acceler
list the probability p(nE) of finding a particle with energy nE, where n is an integer 0, 1, 2, 3, 4. Do this for (a) Maxwell-Boltzmann statistics, (b) Bose-Einstein statistics, and (c) Fermi-Dirac
Heat is extracted from a certain quantity of steam at 100 degrees celsius. as a result, the steam changes into ice at 0 degrees celsius. if this energy were used to accelerate the ice from rest, wha
A boat crosses a river of width 152 m in which the current has a uniform speed of 1.97 m/s. The pilot maintains a bearing (i.e., the direction in which the boat points) perpendicular to the river a
