The A stationary body explodes into two fragments of masses `m_(1)` and `m_(2)`. They are thrown with equal speed against a wall. 2 5. How do their velocities compare? They must have same directions and the same magnitudes. A stationary object explodes into three fragments of equal mass. 30 = 19. 1). Click here👆to get an answer to your question ️ (0 ) 12. The total momentum of the fragments Y. The problem states that m 1 = m 2 and that m 3 = 3 m 1. The center of mass of a system of particles has a constant velocity if: A. The direction to the right is taken as positive. The KE of smaller part is 1. The total kinetic energy transferred to the fragments by the explosion is E. This interaction—one object becoming many, with an increase of kinetic energy of the system—is called an explosion. is the same as the momentum of the projectile immediately before the explosion B. Energetically, that firecracker is very different after it explodes; internal potential energy has become kinetic energy of fragments. The explodes into several pieces. 0 ×104 N⋅s impulse Study with Quizlet and memorize flashcards containing terms like the kinetic energy of the ball, to allow the force of the expanding gases from the gunpowder to act for a longer time, only the mechanical energy (kinetic plus potential) of the puck and more. A stationary particle explodes into two particles of masses m 1 and m 2 which move in opposite directions with velocities v 1 and v 2. If a system begins with a single object with a certain momentum, and that object separates into multiple Study with Quizlet and memorize flashcards containing terms like A very light ping-pong ball moving east at a speed of 4 m/s collides with a very heavy stationary bowling ball. 20 An initially stationary firework explodes and splits into two fragments that move horizontally in opposite directions. A stationary bomb explodes into three pieces. The two pieces of mass m move off at right angles to each other with the same magnitude of momentum mV, as shown in the diagram above. 0 kg fragment? KINETIC ENERGY 183 A B SPEED 4. 0 m/s along the +x-direction and the second fragment moves with a speed of 4. A stationary body explodes into four identical fragments such that three of them fly off mutually perpendicular to each other, View Solution. Two fragments fly off at right angles to each other with velocity 9 m/s and 12 m/s. ⇒ P = mv Where m = mass, and v = velocity. Is this an elastic or inelastic collision and why? elastic, because the balls bounce off each other inelastic, because momentum is not conserved within the system elastic, because kinetic energy is conserved within the system inelastic, because kinetic energy is transferred into sound and A stationary bomb explodes into two parts of masses 3 kg and 1 kg. The energy of the explosion is A shell at the origin explodes into three pieces of masses 1 kg, 2 kg and m kg. Then, the horizontal distance travelled by the other particle from the point of projection is A stationary object explodes, breaking into three pieces of masses m, m, and 3m. This means that the sum of the masses of the four parts must equal the mass of the original shell. Find the kinetic energy of the smaller part. A single object can explode into multiple objects (explosions). an external net force had to act on the stone to accelerate the three pieces d. Therefore, the horizontal velocity of the light block is $ -L /\sqrt{2h/g} $ and it follows that the velocity of the heavy mass is $ (X - L) / \sqrt{2h/g} $ where X is the distance from the launch point to where the heavier mass An initially stationary box on a frectionless floor explodes into two places, places A with mass `m_(A)` and piece B with mass `m_(B)`. I have read that when a bomb explodes into fragments, then total momentum of the system remains conserved. The KE of the smaller parts is : View Solution. They must have the same magnitudes but they could have different directions. The two pieces of mass m move off at right angles to each other with the same magnitude of momentum mV, as shown in the diagram. all three pieces will travel at the same speed b. Which one of the following statements concerning this event is true? A) Kinetic energy is conserved in this process. 5 m/s collides with a stationary object of mass 4. Which one of the following best describes why no injury occurs? a. is less than the momentum of the projectile immediately before the explosion D. How far (in meters) does the lighter fragmen; A stationary shell explodes into two fragments, one fragment 25 times heavier than the other. 1. Two pieces the asked Jul 1, 2019 in Physics by MohitKashyap ( 76. What are the magnitude and direction of the velocity of the piece having mass 3m? ight explodes into several fragments. Which properties of the system are conserved? Kinetic Energy is conserved Momentum and Kinetic Which properties of the system are conserved?
