MO-6 The Meteor Crater in Arizona is about 1,200m wide and 200m deep. It is believed to have been formed 20,000 years ago when a meteor with a mass of 5.0x10"kg moving at 7.2km/s collided and merged with the earth. If the earth had been at rest prior to the collision, what would the speed of the earth have been after this collision? The mass of the earth is 5.98x10"kg. 24
1. In beta decay, an atomic nucleus emits an electron as it turns into another type of nucleus. A 2¹⁰Bi nucleus at rest decays to 210Po. Suppose the emitted electron moves to the right with momentum 5.60 x 10-22 kg m/s. The 210Po nucleus, with mass 3.50 x 10-25 kg, recoils to the left at a speed of 1.14 x 10³ m/s. Momentum conservation requires that a second particle, called an antineutrino, must also be emitted. Calculate the magnitude and direction of the antineutrino's momentum. 210PO 210Bi Before After e ?
James realizes that he can try to get Kevin by having two balls roll down from opposite hills. Ball one is 15kg and is being rolled down a hill of height 32m, ball two is 20kg, and is rolling down in the opposite direction from a height of 18.5m. What are their final velocities at the bottom of the hill? If they are now on a flat plane and collide in a completely elastic collision, what are their final speeds after the collision?

The following question concerns a collision in outer space, far enough from any planets so that the external forces can be considered as negligible. An unmanned spacecraft, having mass 1,500,000 kg and speed 25,000 km/hr collides with a small meteor, having mass 3,000 kg and speed 2,100 km/hr, in the Kuiper belt. a. Prior to the collision, what are the total kinetic energy and total momentum? b. Assuming a head-on collision, in which the meteor becomes lodged into the spacecraft’s body and the two objects move off together, what are the total kinetic energy and momentum after the collision? c. If instead of getting lodged into the spacecraft, the meteor bounced off, would the change in the space craft’s momentum be larger or smaller, or is there not enough information to tell? Explain.
