The air resistance, or drag force, of the rocket is known to be F = -0.75 N. The engine of the rocket has enough fuel to last t = 0.80 s, providing a total impulse of 7₂ = 2.20 N-s, which is called the thrust stage. After the engine runs out of fuel, the rocket coasts to its maximum height before falling back to the ground, which is called the coast stage. Draw force diagrams of the rocket during the two stages of the problem: Thrust Stage Coast StageA particle of mass m moves with a momentum of magnitude p. Express p in terms of KE.

- QUESTION An object has a kinetic energy of 300 Joule and a momentum of magnitude 45 kg-m/s. Find the mass and the velocity of the object.Hi, can you please give me a solution why the answer to this question is 6 m/s? Thanks. When a light beach ball rolling with a speed of 6.0 m/s collides with a heavy exercise ball at rest, the beach ball's speed after the collision will be, approximately Answer: 6m/sIn the four momentum treatment of relativistic particle collisions or decays, The mass of a particle is different for various observers. O Momentum and energy are still conserved in any inertial frame of reference. O The energy equals the sum of the momentum, pc, plus the mass, mc2. O The momentum and energy for a process are the same in all frames of reference.
