You’re playing with two of the carts (each with mass m) that you used in Activity 27a.

Initially, these two carts are moving toward each other with the same initial speed vi along the track.

The carts collide and the result is one of these ﬁnal states:

(a) Assume that the carts hit each other and stop so that the ﬁnal state of the system has both carts just sitting still (not moving). Draw a Momentum Chart for this situation. Make a separate row for each cart.

(b) Assume that the carts bounce oﬀ each other so that the ﬁnal state of the system has each cart moving opposite to its initial motion but with their speeds unchanged. Draw a Momentum Chart for this situation.

(c) As in (b), assume that the carts bounce oﬀ each other but now assume that the ﬁnal speeds are smaller than the initial speeds, equal and in opposite directions. Draw a Momentum Chart.

(d) For each case above, does the total momentum of the system that contains the two carts change? How do the Momentum Charts help you answer this question?

(e) Is the total kinetic energy constant for all three cases? How do you know?

Please work on the following on graph paper

Suppose you’re playing a game where you consecutively roll 3 dice. After each roll you may choose to either roll the next dice or sacrifice one die to reroll any number of the previous dice. If you get a number greater than 5 you win, but if you roll doubles or a number less than 6 you lose. Considering each roll a separate state what is the approximate branching factor? Justify. Draw the full state space considering only the number...

You’re playing pool and you line up a shot on the 3 ball. You want the 3 ball to be deflected by an angle of (Theta)3 = 25(Degrees) at a velocity v3 = 1.3 m/s so that it will make it into a side pocket. What initial velocity must you give the cue ball in order to make this shot and what will be the velocity and angle of the cue ball following the collision? Recall that the mass of...

Two loudspeakers 6.0 m apart are playing the same frequency. If you stand 10.0 m in front of the plane of the speakers, centered between them, you hear a sound of maximum intensity. As you walk parallel to the plane of the speakers, staying 10.0 m in front of them, you first hear a minimum of sound intensity when you are directly in front of one of the speakers. PART A What is the frequency of the sound? Assume a...
