1. An object is at x = -10 m moving at a constant velocity of 10 m/s. What would be the position of the body after 10 seconds? 2. Two siblings, Kaeya and Diluc, decided to take a walk around Mondstadt, following its perimeter guarded by walls. For those who haven't seen Mondstadt, you can imagine it as a city of walls with beautiful German architecture. Let's roughly assume that the walls are encircling it in a perfect circle. Both Kaeya and Diluc started at the front of the huge city gate (marked at 0 degrees), and they walk separately, away from each other. Assuming that radius of the circular city of Mondstadt to be 500 m, and the constant walking speed of both siblings to be 0.5 m/s, how long until the siblings achieve the greatest separation distance between them? 3.

The Vomit Comet. In microgravity astronaut training and equipment testing, NASA flies a KC135A aircraft along a parabolic flight path. As shown in Figure P3.45, the aircraft climbs from 24 000 ft to 31 000 ft, where it enters a parabolic path with a velocity of 143 m/s nose high at 45.0 and exits with velocity 143 m/s at 45.0 nose low.
