calculate the magnitude of the linear momentum for the following cases. A. a proton with a mass 1.67 x 10-27 kg moving with a speed of 4.80 x 10^6 m/s B. a 15.0-g bullet moving with a speed of 330 m/s C. a 72.0-kg sprinter running with a speed of 12.5 m/s

B Two balls roll horiztonally off the edge of a 1.29 m tall table. Ball A has a mass of 2.4 kg and is moving at 1.4 m/s when it leaves the table. Ball B has a mass of 4.9 kg and is moving at 7.7 m/s when it leaves the table. Both balls leave the table at the same instant. Which ball hits the ground first? Ball B Same Time O Ball A Cannot Tell How much time does it take Ball B to hit the ground after leaving the table? How far from the edge of the table does Ball A land? (horizontal distance) m How far from the edge of the table does Ball B land? (horizontal distance) m

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.
