A560-g squirrel with a surface area of 930cm2 falls from a 5.0-m tree to the ground. estimate its terminal velocity. (use a drag coefficient for a horizontal skydiver.) what will be the velocity of a 56-kg person hitting the ground, assuming no drag contribution in such a short distance

Explanation:

Terminal velocity is given by:

Here, m is the mass of the falling object, g is the gravitational acceleration,   is the drag coefficient, is the fluid density through which the object is falling, and A is the projected area of the object. in this case the projected area is given by:

Recall that drag coefficient for a horizontal skydiver is equal to 1 and air density is .

Without drag contribution the motion of the person is an uniformly accelerated motion, thus:
