- A neutron with mass m1 moving with velocity v0 collides elastically and head-on with a target particle with mass m2 that is at rest. After the collision, the neutron moves with velocity v1f and the target particle moves with velocity v2f. Write the two equations that express conservation of momentum and conservation of kinetic energy for this collision. Consider collisions of the neutron (mass = 1.0 atomic mass unit (amu)) with the following stationary target particles an electron (mass =5 x 10-4 amu) a proton (mass = 1.0 amu) the nucleus of a carbon atom (mass = 12.0 amu) the nucleus of a uranium atom (mass = 238 amu) Match some of the collisions above with each of the following head-on collisions that we discussed in lecture: the collision between two billiard balls, one of the billiard balls initially at rest the collision between a ping pong ball and a bowling ball, the ping pong ball initially at rest the collision between a ping pong ball and a bowling ball, the bowling…arrow_forwardA golf ball of mass m = 0.18 kg is dropped from a height h. It interacts with the floor for t = 0.11 s, and applies a force of F = 17.5 N to the floor when it elastically collides with it. Randomized Variablesm = 0.18 kgt = 0.11 sF= 17.5 N Write an expression for the ball's velocity, v, in terms of the variables m, t, and F, just after it rebounds from the floor. (Hint: The fact that the collision is elastic is important when solving this problem.) What is the magnitude of the ball's velocity v, in meters per second, right after it rebounds? How high h, in meters, will the ball travel on the rebound?arrow_forwardA proton of mass m undergoes a head on collision with a stationary atom of mass 13m. If the initial speed of the proton is 455 m/s, find the speed of the proton after the collision.arrow_forward
- An important fusion reaction in both hydrogen bombs and controlled-fusion reactors is the “DT reaction,” in which a deuteron and a triton (nuclei of heavy hydrogen isotopes) combine to form an alpha particle and a neutron with the release of much energy. Use momentum conservation to explain why the neutron resulting from this reaction receives about 80% of the energy, while the alpha particle gets only about 20%.arrow_forwardAn astronaut of mass 180 kgkg including his suit and jet pack (when the jet pack is FULL and no gas has been used yet) wants to acquire a velocity of 1.6 m/sm/s to move back toward his space shuttle.Assuming the jet pack can eject gas with a velocity of 60 m/sm/s , what mass of gas will need to be ejected?arrow_forwardTwo atoms collide while moving in a gas. The larger atom has a mass M1 = 6 Daltons and a speed v1 = 230 m/s, while the smaller has a mass M2 = 1 Daltons (D). During the collision both atoms simply bounce off each other. They do not change their speeds, but after the collision they each reverse their directions, bouncing straight back. (You may express your results using the mass unit "Daltons". 1 Dalton is approximately equal to the mass of a proton or neutron and is defined as one-twelfth the mass of a single neutral carbon-12 atom in its ground state.) What is the magnitude of the change in the momentum, Δp1, of mass M1?arrow_forward
- An object A moving with velocity v collides with a stationary object B. After the collision, A is moving with velocity 2 1 v and B with velocity 3 2 v. Find the ratio of their masses. If, instead of bouncing apart, the two bodies stuck together after the collision, with what velocity would they then move?arrow_forwardTwo solid iron spheres of masses m and 2m respectively, are suspended from two inextensible ropes of length l. We separate the ball of mass m from its equilibrium position at an angle α, keeping the string extended in the same plane. The mass is released and collides elastically with the sphere of mass 2m. The speed of the sphere sphere of mass m immediately after the collision is:arrow_forwardA bowling ball onboard a space station is floating at rest relative to the station and an astronaut nudges a Ping-Pong ball toward it at speed v, initiating a perfectly elastic headon collision. Which answer is closest to the Ping-Pong ball’s speed after the collision? (a) 0 (b) v/2 (c) v (d) 2v (e) 3varrow_forward
- Professional Application One of the waste products of a nuclear reactor is plutonium-239 (239Pu). This nucleus is radioactive and decays by splitting into a helium-4 nucleus and a uranium-235 nucleus (4He+235U), the latter of which is also radioactive and will itself decay some time later. The energy emitted in the plutonium decay is 8.401013 J and is entirely converted to kinetic energy of the helium and uranium nuclei. The mass of the helium nucleus is 6.681027 kg, while that of the uranium is 3.921025 kg (note that the ratio of the masses is 4 to 235). (a) Calculate the velocities of the two nuclei, assuming the plutonium nucleus is originally at rest. (b) How much kinetic energy does each nucleus carry away? Note that the data given here are accurate to three digits only.arrow_forwardDuring a lunar mission, it is necessary to increase the speed of a spacecraft by 2.2 m/s when it is moving at 400 m/s relative to the Moon. The speed of the exhaust products from the rocket engine is 1000 m/s relative to the spacecraft. What fraction of the initial mass of the spacecraft must be burned and ejected to accomplish the speed increase?arrow_forwardBall having mass 3.4kg and velocity 7.2m/s travels to the east. Impulse given at point O, makes it change direction to north with velocity 2.2 m/s. What is the direction of the given impulse, measured in unit of degrees, if the angle is defined as between the horizontal direction (east) and the impulse?arrow_forward
