Estimate the magnitude of the force, in lbf, exerted on a 12-lb goose in a collision of duration 10^-3s with an airplane taking off at 150 miles/h.

The collision force is 81987.577 lbf

Explanation:

Apply Newton’s second law of motion for required collision force exerted on the goose.

Given:  

Mass of goose is 12 lb.

Time of collision is s.

Taking off speed is 150 miles/h.

Calculation:  

Step1

Convert take off speed in ft/s as follows:

v = 220 ft/s

Step2  

Collision force is calculated as follows:

F = 81987.577 lbf.

Thus, the collision force is 81987.577 lbf.
