In a football game, one player (a "tackle") running at a constant speed of 5 m/s tackles another player (a "receiver") who is initially stationary. The two players fly off together horizontally at 3 m/s, before they hit the ground and begin to slow down. If the mass of the tackle is 140 kg,

a.) What is the mass of the receiver?
[_________] kg

b.) Calculate the kinetic energy of the tackle-receiver system before and after the collision.

\[ KE_{\text{sys, i}} = \_________\ \text{J} \]

\[ KE_{\text{sys, f}} = \_________\ \text{J} \]

(Did the mechanical energy of the system increase, decrease, or stay the same?)

c.) What kind of collision is this?
[Dropdown menu]
- ---Select---
- elastic
- somewhat inelastic
- completely inelastic

(Did you need to do part b to be able to answer this?)

A rocket is propelled forward as very high speed gases are ejected out of its back. Which one of the following is the best explanation as to why the rocket is propelled forward? The high speed gases push on the rocket as they are ejected and propel it forward. B) The rocket is propelled forward because both energy and momentum must be conserved. The rocket is propelled forward due to the conservation of momentum. Because the gases are pushing against the air, the air propels the rocket forward.
