A 68 kg diver jumps off a platform and strikes the water at a speed of 14.7 m/s, then slows to a stop underwater in 0.35 s. What force does the water exert on the diver?

that tool is called an altimeter which measures your altitude which can be used to tell which atmosphere you are currently in, including the stratosphere.

hope this ! : )

that would be because of both gravity and friction. so     c
