On your first trip to Planet X you happen to take along a 215 mass, a long spring, a meter stick, and a stopwatch. You're curious about the free-fall acceleration on Planet X, where ordinary tasks seem easier than on earth, but you can't find this information in your Visitor's Guide. One night you suspend the spring from the ceiling in your room and hang the mass from it. You find that the mass stretches the spring by 31.5 . You then pull the mass down 11.4 and release it. With the stopwatch you find that 11 oscillations take 16.6 .
Part A What is the value of gravity? =
Part B What is the spring constant of your spring? =
Two water reservoirs are open to the atmosphere. The manometer contains mercury with the density of 13,600kg/m cubed. What is the difference in elevation if the manometer reading is 25cm.
Find out the height from which you would have to drop a ball so that it would have a speed of 9.7 m/s just before it hits the ground.
The nucleus in an iron atom has a radius of about 4.0 X 10-15 m and contains 26 protons, What is the magnitude of the gravitational force between those same two protons
A 4.1kg bucket of water is raised from a well by a rope. If the upward acceleration of the bucket is 3.3m/s2, find the force exerted by the rope on the bucket.
An undamped oscillator has period 0 = 1.000 seconds, but I now add a little damping so that its period changes to 1 = 1.001 seconds. What is the damping factor ? By what factor would the amplitude of oscillation decrease after 10 cycles.
assume a block of mass 25.0 kg rests on a horizontal plane, and the coefficient of static friction between the surfaces is 0.220. what is the actual static frictional force that acts on the block if an external force of 25.0 N acts horizontally on..
