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. Two blocks, each of mass m = 6.90 kg , are connected by a massless rope and start sliding down a slope of incline θ = 36.0 ∘ at t=0.000 s. The…
A curved nozzle deflects water steadily, at a rate of 30 kg/s, in a horizontal pipe upward by an angle of 45° as shown in figure 2. The nozzle discharges water into the atmosphere. The cross sectional area of the elbow is 150 cm2 at location 1 and 25 cm2 at location 2. The height difference between locations 1 and 2 is 0.40 m. The total mass of the nozzle and the water in it is 50 kg. The flow velocities in the pipe can be assumed to be uniform. (a) Calculate the velocity at locations 1 and 2.(b) Calculate the gauge pressure at location 1. (c) Consider a Control Volume that encompasses the nozzle and passes though locations 1 and 2. Calculate the external reaction force (magnitude and direction) that the horizontal section of pipe exerts on the Control Volume. This reaction force is equivalent to the force required to hold the nozzle static and is called an anchoring force. Figure 2. Curved nozzle discharging to the atmosphere.
A rocket lifts off from Earth initially at a mass of 50,000 kg. If it burns 40,000 kg of fuel during 40 seconds, it increases its speed by 5 km/s. 1. What is the exhaust velocity of the rocket? 2. What is the mass loss rate of the rocket? 3. What is the thrust of the rocket?
During terrible weather at a ski-flying world championship, a ski jumper tried to adjust for bad conditions midway down the ramp but completely lost control and tumbled wildly off the side at its bottom into a scattering crowd. The 73-kg jumper left the ramp about 45 m lower than his starting position. If the ski jumper had simply fallen straight down 45-m rather than skiing down a ramp, would his kinetic energy increase?
During an Olympic 100-m sprint race, Usain Bolt, the world record holder in that race, quickly accelerates to his top speed of 12.4 m/s. Analysis of his technique has shown that each of his feet make contact with the ground for 0.0800 s, exerting a force of magnitude 2.80 x 10° N during this contact. This allows the 94.0 kg Bolt to leap forward and remain airborne for 0.120 s until the next foot touches the ground. (Ignore air resistance.) (a) What are the magnitudes of the horizontal and vertical components of the force (in N) Bolt's feet exert on the ground? (Round your answers to at least three significant figures.) horizontal N vertical (b) Assuming that the sprinter accelerates at a constant rate while his feet are in contact with the ground and does not slow down when he is airborne, by what amount does Bolt's horizontal speed (in m/s) increase with each step? (Round your answer to at least three significant figures.) m/s (c) Assuming that the sprinter's speed increases at a…
During the entry of the space shuttle into the earth’s atmosphere, maximum stagnation point heating occurs at the trajectory point corresponding to an altitude of 68.9 km, where ρ∞ = 1.075 × 10−4 kg/m3, and a flight velocity of 6.61 km/s. At this point on its entry trajectory, the shuttle is at a 40.2 degree angle of attack, which presents an effective nose radius at the stagnation point of 1.29 m. If the wall temperature is Tw = 1110 K, calculatethe stagnation point heating rate.

A block with mass 0.400 kg is on a horizontal frictionless surface and is attached to a horizontal compressed spring that has force constant k=200N/m The other end of the spring is attached to a wall. The block is released, and it moves back and forth on the end of the spring. During this motion the block has speed 3.00 m/s when the spring is stretched 0.160 m. During the block's motion, what is the maximum distance the spring is compressed from its equilibrium position? When the spring has its maximum compression, what is the speed of the block and what is the magnitude of the acceleration of the block?
