As it is sliding across ice, an internal explosion breaks an 80 kg object into two pieces. One piece has a mass of 33 kg and moves off with a speed of 15 m/s at an angle of 40° relative to the initial path of the object. The object was initially moving at 20 m/s. (a) What is the speed and direction of the other piece after the explosion? Be sure to explain how you are able to determine this. (b) Compare the kinetic energy of the single object before the explosion to the total kinetic energy of the two pieces after. Explain how this relates to the term 'explosion'.

From what might be a possible scene in the comic book The X-Men, the Juggernaut (mJ) is charging into Colossus (mC) and the two collide. The initial speed of the Juggernaut is vJi and the initial speed of Colossus is vCi. After the collision, the final speed of the Juggernaut is vJf and the final speed of Colossus is vCf as they each bounce off of the other, heading in opposite directions. a. What is the impulse experienced by the Juggernaut? b. What is the impulse experienced by Colossus? c. In your own words, explain how these impulses must compare with each other and how they are related to the average force each superhero experiences during the collision.

A space probe, initially at rest, undergoes an internal mechanical malfunction and breaks into three pieces. One piece of mass ml = 48.0 kg travels in the positive x-direction at 12.0 m/s, and a second piece of mass m2 = 62.0 kg travels in the xy-plane at an angle of 105 at 15.0 m/s.
