A 560-g squirrel with a surface area of 930 cm2 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?

Solution 22PE :

Step 1 of 4:-

The mass of the squirrel is, .

Surface area is, .

The value of acceleration due to gravity is, .

The drag coefficient is taken same as a horizontal skydiver, which is, .

The height from which the squirrel jumped is, .

Step 2 of 4:-

The terminal velocity will be,

--------------------------(1)

Where is the mass of the object,

is the acceleration due to gravity.

is the density of air,

is the area of projected object,

is the drag coefficient.

Surface area is, .

The air density is, .
