Principle of Linear Impulse and Momentum for a System of Particles
To apply the principle of linear impulse and momentum to a system of particles.
Integrating the equation of motion, as applied to all particles in a system, yields
∑mi(vi)1+∑∫t2t1Fidt=∑mi(vi)2
where mi is the ith particle's mass, vi is the ith particle's velocity, and Fi is the external force that acts on the ith particle. This relationship states that the sum of the initial linear momenta, at time t1, and the impulses of all the external forces acting between times t1 and t2 is equal to the sum of the linear momenta of the system, at time t2. If the system has a mass center, G, the expression becomes
m(vG)1+∑∫t2t1Fidt=m(vG)2
This expression allows the principle of linear impulse and momentum to be applied to a system of particles that is represented as a single particle.

A communications satellite weighing 10,000 lb, including fuel, was injected from a space shuttle in low orbit around the earth. After the satellite slowly drifted to a safe distance from the shuttle, its engine was operated to increase its speed by 8000 ft/s as the first step in its transition into a geosynchronous orbit. It is known that fuel is released with a relative speed of 13,750 ft/s. Determine the weight of fuel consumed in the process that took place.
choices of the correct answer:
7930 lbs
9930 lbs
4410 lbs
5430 lbs
2230 lbs

- A constant force P is applied to a piston and rod of total mass m to make them move in a cylinder filled with oil. As the piston moves, the oil is forced through orifices in the piston and exerts on the piston a force of magnitude kv in a direction opposite to the motion of the piston. Knowing that the piston starts from rest at t= 0 and x = 0, show that the equation relating x, v, and t, where x is the distance traveled by the piston and v is the speed of the piston, is linear in each of these variables.arrow_forwardA spacecraft is moving in gravity-free space along a straight path when its pilot decides to accelerate forward.
