Find a vector parametrization of the ellipse centered at the origin in the xy-plane that has major diameter 1616 along the x-axis, minor diameter 1212 along the y-axis, and is oriented counter-clockwise. your parametrization should make the point (8,0)(8,0) correspond to t=0t=0. use tt as the parameter in your answer.

2.22/3.33 points | previous answers tamucolphysmechl1 4.pre.002. ask your teacher my notes question part points submissions used on a frictionless air track, a blue glider with mass 0.200 kg is moving to the right with a speed of 8.00 m/s. it strikes a red glider that has mass 0.600 kg and that is initially at rest. after the collision, the blue glider is moving to the left with a speed of 2.40 m/s. (a) what are the magnitude and direction of the velocity of the red glider after the collision? magnitude 3.33 m/s correct: your answer is correct. direction correct: your answer is correct. (b) is this collision elastic?
