A helicopter lifts 35m vertically into the air and then comes back down to the ground. What is the distance of the helicopter’s flight?

What is the displacement of the helicopter’s flight?

Explanation:

Distance = Total path length = 35m + 35m = 70m

Displacement = Final - Initial position = 0m

spare some change and give it to the poor

explanation:

plz : ((

when two balls of the different masses are dropped from equal height, they reach the ground at the same time .this is because they experience the same acceleration.

the acceleration is independent of mass.

thus when they are dropped they will always maintain the same velocity and travel the same distance (neglect air resistance of course) at the same time.
