Question
A helicopter is flying at a height of 1500 m. There is a helipad which is just below the helicopter at a height of 600 m from the ground. Taking upward movement of the helicopter as positive and downward movement as negative. Find the distance of helipad from the helicopter? How much time will it take for the helicopter to reach the helipad if the speed of the helicopter is 50 meters per second?

Upward movement is taken as positive while downward movement is taken as negative. Hence, from the question we can conclude that helicopter is moving downward. So, the distance of helipad from the helicopter will be negative integers.
=−1500m+600m
=−900m.
Given that the speed of the helicopter is 50 meters per second.
Total distance to be covered = 900 m
Time taken by the helicopter to reach the helipad = 900 ÷ 50 =18 seconds
Hence, the helicopter will reach the helipad in 18 seconds.
