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?
