In this problem, the distance units are meters and the time units are sec- onds. Consider two particles p and q in 2-D or 3-D space, with respective masses n kg and m kg, that approach cach other, collide elastically, and then bounce off. Suppose is the initial constant velocity of p, and v is the initial velocity of q (see the "Before Collision" picture below). After the collision, p and q have constant velocities of us ‡ and v} ‡ ♂, respectively (see the "After Collision" picture below). # Beforeli the prepision After the collision (collision point р Constant 2-D3-D ● vi Constant) velocities VE - (1) Calculate a formula for the radian angle 0 € [0, π] between the path of p and the path of q after the collision, in terms of the scalar quantities m, n, ||||and |||| (and only these quantities). (2) In the case where p and q have the same mass, calculate exactly.

Suppose two particles are traveling along the space curves r1(t)=< t2,, 8t-16, t2 > and r1(t)=< 3t+4, t2, 5t-4, >.  A collision will occur when the two particles arrive at the same point at the same time.  Find any time(s) and location(s) when and where the particles collide

In a very busy off-campus eatery one chef sends a 221 g broccoli-tomato-pickle-onion-mushroom pizza sliding down the counter from left to right at 1.59 m/s. Almost simultaneously, the other chef launches a 315 g veggieburger (with everything, but hold the horseradish) along the same counter from right to left at 2.27 m/s. The two delicacies collide head on at the given speeds. The counter is practically friction free due to accumulated grease. The two delicacies merge into a single, unbelievably savory serving.   In what direction does the merged meal move, if it moves at all? a. to the right b. to the left  c. does not move   At what speed does it move in m/s? (positive number).

I need the answer as soon as possible
