The block's displacement (or change in position) in reference frame R during the period AL * is either upward, downward, or equal to zero? Explain. (Use the velocity arrow from section c.i. to guide your response.) Does the block have an upward, downward, or no net force? Explain. Use the acceleration arrow from section c.i. to help you answer this question: Is the net force doing more work on the block than it is taking off? Explain. Based on your responses to the preceding two questions, how would you answer this question? Test to see whether you've answered section c.iii correctly in terms of net force work done on the block.

2-D Collision and Explosion
You are analyzing the possible defenses for an asteroid that is going to crash into Earth.
Initially, the asteroid of mass mą is traveling to the left with speed v . A missile of mass mm with initial velocity vmi to the right collides with the asteroid, and embeds itself inside the asteroid. See the figure below.

Find the common final velocity of the missile and asteroid after the collision.
Use an x axis with positive pointing to the right.
Solve algebraically first, then use the following values for the parameters to get a value for Ve :
ma = 2.3000E+9 kg
Mm = 9.2000E+7 kg
Vaix = -1800 m/s
