Impulse and momentum change/varying force. A 10-kg asteroid is traveling through space at 2 m/s toward a spaceship
A person lying on an air mattress in the ocean rises and falls through one complete cycle every 5.5 seconds. The crests of the wave causing the motion.
Tsunamis are fast-moving waves generated by underwater earthquakes. In the deep ocean their amplitude is barely noticeable.
Blocks of equal mass M sits on a plane inclined at 30 degrees to the horizontal. The coefficient of friction between the lower block (A) and the plane
This system is suspended from end A. A horizontal force F is applied at the other end, D. Find the equilibrium configuration.
Express your answer in terms of some or all of the variables: k, m, and A.Express your answer in terms of some or all of the variables: k, m, A, and t.
What are the differences among meteorites, asteroids, and comets? What roles did each play in the formation of the Moon?
How long does it take the pendulum swinging from rest to reach the position ?=0. How long does it take to reach ?=0 a second time?
As mentioned before, our asteroid is in the shape of a sphere and has a mass of 1000 kilograms. Determine the density (in grams per cubic centimeter)
The farther the object falls, the faster it is moving when it hits the ground. For each second that an object falls.
A bead slides without friction around a loop-the-loop. The bead is released from a height of 8.5 m from the bottom of the loop-the-loop.
On Wednesday 9th of November 2011 asteroid 2005 YU55 passed by the Earth at a distance of 323,469 km, which is closer than the Moon.
If the asteroid is moving at a constant speed in its orbit, does this also mean it is moving at a constant velocity? Explain your answer.
Measurements of 2008 TC3â??s orbit in October 2008 led to an initial estimate that it had a 0.3% probability of impacting the Earth in 10 yearsâ?
Use a graphical method to estimate the velocity of the ball after being struck, assuming the ball is being served so it is nearly at rest initially.
Asteroid 2008 TC3 was determined from observations to have a semi-major axis of 1.296 AU and eccentricity of 0.303.
A small asteroid is moving in a circular orbit of radius R_0 about the sun. This asteroid is suddenly struck by another asteroid.
Use the discriminant to determine whether the following equations have solutions that are: two different rational solutions.
Explain the meaning of the slope and area of the velocity vs. time for this object during this time interval.
Number sequences and series occur throughout the study of mathematics and take on a special variety of applications.
A particle moves along the x-axis. Its position varies with time and is given by equation x =-6t + 3t^2 where x is in metres and t is in seconds.
With regard to the above question, could any part of the speed line ever become perfectly vertical? Why or why not?
Due to friction with the Earth's atmosphere, a large static electric charge could build up on our plummeting asteroid fragment. Would you expect our fragment
Sketch the average velocity line in your graph from part e. Make sure all of your lines are labeled in the graph.
Which of the following can be considered a definition of "theory?"
