Show by algebraically reasoning that your gravitation acceleration towards an object of mass M a distance d away is a=GM/d^2
What is the free fall acceleration in a location where the period of a 2.15 m long pendulum is 2.94s?
A stone is dropped from the top of a cliff. The splash it makes when striking the water below is heard 3.33 s later. How high is the cliff?
If m1 = 3.12 kg, m2 = 2.74 kg, and m3 = 2.5 kg, to the nearest hundredth of a nJ what is the potential energy of the configuration?
Rotating Space Stations. One problem for human living in outer space is that they are apparently weightless
Three objects are positioned along the x axis as follows: 4.4 kg at x = +1.1m, 3.7 kg at x = -0.80m, and 2.9 kg at x = -1.6 m.
THERE IS A BLOCK OF SIDE X METRES RESTING ON A FRICTIONLESS SURFACE A FORCE F IS APPLIED AT THE LEFT TOP OF THE BOX
When scientists are trying to understand a particular set of phenomena, they often make use of, in a scientific sense, a kind of analogy or mental image
Block A of mass m1 on a smooth frictionless surface being pulled to the right by the force of gravity on block B with mass m2 by means of the attached string
Isaac Newton investigated the nature of gravity in holding stellar and planetary systems together.
Ocean tides are produced primarily by the gravitational attraction of the Moon. Explain how this attraction gives rise to two tidal "bulges"
When the net force that acts on a hockey puck is 10 N, the puck accelerates at a rate of 50 m/s^2. Determine the mass of the puck.
A small block of mass 0.09 kg is placed against a compressed spring at the bottom of a frictionless track that slopes upward
Describe the properties of life on Earth
To measure the static friction coefficient between a 1.9 kg block and a vertical wall, the setup shown in the drawing is used.
Find the acceleration of gravity g for the following mass distribution. The mass distribution consists of an infinitely long "wire" of radius
Segments of 12mt long steel rails are laid end to end when the temperature is -12 degree C. A space is left between rail segments to allow for thermal expansion
The Moon is in orbit around the Earth. Is the moon pulled by the Earth's gravity; or, is the Earth pulled by the Moon's gravity; or, both. Explain.
A 75 kg man just before contact with the ground has a speed of 6.4 m/s.
Consider a monatomic ideal gas that lives at a height z above sea level, so each molecule has potential energy mgz in addition to its kinetic energy.
A ball dropped to the floor rises to a height less than its original height. Discuss some of the energyconversions that take place in a system like this.
Waves - What is the value of g, the acceleration due to gravity, on Planet X?
Young David who slew Goliath experimented with slings before tackling the giant. He found that with a sling of length .598 m, he could develop a rotation
