Physics - Potential Energy - Gravitational Force
A satellite has a mass of 100 kg and is located at 2.00 x 10^ 6 m above the surface of earth. (A) What is the potential energy associated with the satellite at this location?
(B) What is the magnitude of the gravitational force on the satellite?
An 88 kg spacewalking astronaut pushes off a 640kg satellite, exerting a 640N force for the 0.60 s it takes him to straighten his arms.
A 2000 kg car traveling at a speed of 23m/s skids to the halt on wet concrete where = 0.60. How long are the skid marks.
Two sound sources radiating in phase at a frequency of 560 Hz interfere such that maxima are heard at angles of 0 and 25° from a line perpendicular to that joining the two sources. Find out the separation between the two sources. (Wave velocity of..
Physics: Simple Harmonic Oscillator, Traveling waves are set up in a pair of long strings by a simple harmonic oscillator. The strings have identical mass densities of 5.1 grams/meter.
A 105 granite cube slides down a 40 frictionless ramp. At the bottom, just as it exits onto a horizontal table, it collides with a 265 steel cube at rest. How high above the table must the granite cube be released to give the steel cube a speed of..

If the heavier fragment lands back at the equal point from which the shell was launched, where will lighter fragment land and how much energy was released in the explosion.
Approximately how many atoms make up our planet? For simplicity, suppose the average atomic mass of the atoms is 14 . Avogadro's number gives the number of atoms in a mole.
A 9.10 kg board is wedged into a corner and held by a spring at a 50° angle, as the Illustrating shows. The spring has a spring constant of 196 N/m and is parallel to the floor.
