15. A car travels at a constant velocity of 30 m/s. How long does it take to travel 126 meters? A car starts from rest and accelerates for 10 seconds at 3.5 m/s2. How far does it travel?

A search and rescue helicopter travels at constant speed in a horizontal plane. The figure below shows a portion of the path traveled by the helicopter, as viewed looking down from above. The helicopter's path includes three straight portions between points "1" and "2", points "4" and "5", and points "7" and "8", each of which has a length of 4000 m, as shown in the figure. It takes the helicopter 2000 seconds to travel along each of these straight portions of its path. The semi-circular portions of the path (also shown in the figure) have the same radius R=500m. +y YNorth) 8. 4 4000 m A semi-circle is one half of a circle. East 6.
