Question

To use the principle of linear impulse and momentum to relate a force on an object to the resulting velocity of the object at different times.

The equation of motion for a particle of mass mcan be written as

?F=ma=mdvdt

By rearranging the terms and integrating, this equation becomes the principle of linear impulse and momentum:

??t2t1Fdt=m?v2v1dv=mv2?mv1

For problem-solving purposes, this principle is often rewritten as

mv1+??t2t1Fdt=mv2

The integral ?Fdt is called the linear impulse, I, and the vector mv is called the particle's linear momentum.

Part A

A jetliner of mass 8.69

Explanation / Answer

Favg * 1.1 = 8.69 * 10 4 * 78.5

Favg = 6.2 * 10 6 N
