Chapter 3, Problem 8RAT

The amount of air resistance on a 0.8-N flying squirrel for terminal speed is

(a) less than 0.8-N.

(b) 0.8-N.

(c) more than 0.8-N.

(d) dependent on the orientation of its body.

To determine

The correct option for the statement "The amount of air resistance on a flying squirrel for terminal speed is".

Answer to Problem 8RAT

The correct option for the statement "The amount of air resistance on a 0.8-Nflying squirrel for terminal speed is" is option (b).

Explanation of Solution

Terminal velocity is defined as the maximum velocity obtained by the moving object when the resultant net force acting over the object is equal to zero in magnitude. If an object is flying in the air, then at the terminal velocity, the total drag force and buoyancy force exerted by the air is equal to the gravitational force acting over the object.

The terminal velocity of the object also depends upon the orientation of the object because, at a different orientation, the drag force or friction force may be changed. Thus, the terminal velocity of the squirrel is 0.8N . From this, it is concluded that option (b) will be correct in the given options.

Conclusion:

Therefore, the correct option for the statement "The amount of air resistance on a 0.8-N flying squirrel for terminal speed is" is option (b).
