The two cars of masses m1 and m2, collide at an intersection. Before the collision, car 1 was traveling eastward at a speed of v1, and car 2 was traveling northward at a speed of v2. After the collision, the two cars stick together and travel off in the northeast direction. a) find the tangent of angle theta.

the independent variable, the one that is intentionally manipulated, is whether or not the car hits the barrier.

the dependent variable, the one that you measure the response in, is the distance that the washers travel.

i think the answer is a, hope this is right, that would be my best guess.

kepler used the data from tycho blahe (his mentor) to construct the laws of planetary motion.

when heated, the valance electrons increased their speed and transferred the heat from electron to electron.   i just took the test.
