The superman modeled as a rocket.

Question

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.

A. Answer the following questions with a scientific explanation. Use the given linesto answer each item. Supposed that you have to jump from a second story window. Which would you prefer? To jump onto a wood or a concrete surface? Which has a greater momentum, an airplane parked in a hangar or a car going down a hill?

A 2000 kg car is being pushed from rest by a bulldozer. The car is pushed for 10 seconds along a rough road with a coefficient of friction of 0.05. The car experiences impulse of 10,000 kgm/s. a. What net force acts on the car? b. What is the acceleration of the car? c. What is the work done by the non-conservative forces as the car moves along the road? acar
