13. An elephant weights 5000 N and one elephant foot has an area of 0.5m². Calculate the total pressure
as you go deepen the elephant exerts from the ground.
P-5000/0.5m?
P- & F/A

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.
