## Homework Statement

A biologist working 80 meters high in the Amazon tree canopy drops her pliers used for crimping

bands on animal legs.

1) Assuming the pliers hit nothing on the way to the ground, how fast will the pliers be moving when

they reach the ground?

2) When the pliers hit the forest floor, they come to a stop in 0.05 seconds. What force does the ground

exert on the 400 gram pliers?

3) How deep do the pliers sink into the ground when they come to a stop?

## Homework Equations

I don't know what equations to use.

## The Attempt at a Solution

i need maybe a guide line on how to do this problem.

Thank you
