Two events occur in an inertial system k as follows. event 1: x1 = 0.7a, t1 = 2a/c, y1 = 0, z1 = 0 event 2: x2 = 2a, t2 = 1.1a/c, y2 = 0, z2 = 0 is there a frame k' in which the two events occur at the same place? yes no if "yes", then determine the velocity of k' relative to k. if "no", then determine the velocity of the frame in which the two events are simultaneous. express the velocity vector using the variables a and c and the unit vectors, i, j, and k; for example, 2i + 2j is a vector which bisects the x and y axes?

(0,-3) see attached graph

step-by-step explanation:

a. to solve the system, graph the two equations.

x = y+3 becomes y=x-3 has m=1/1 and b=-3. start at (0,-3) on the y-axis and plot a point. then move up 1 unit and 1 unit to the right. plot a point and connect.

y=-4x+3 has m =-4/1 and b=-3. start at (0,-3) on the y-axis and plot a point. then move down four units and to the right 1 unit. plot a point and connect.

the solution is the point (x,y) where the two lines intersect. by the graph below it is (0,-3).

b. to solve by substitution, substitute y = -4x-3 into x= y+3

x= (-4x-3) +3

x=-4x

5x=0

x=0

now substitute x = 0 back in to find y.

y= -4(0)-3

y=0-3

y=-3

solution is (0,-3)

c. use elimination by adding the equations together.

x-y=3

4x+y=-3

5x=0

x=0

then substitute into one equation to find y.

y=-4(0)-3

y=-3

pay attention in your classes and concentrate the best thing you can do to raise your test scores is to pay attention when you're supposed to be learning the material: in class!

take good notes.

do your homework.

use mnemonics and other tricks.

do practice tests.
