1. Graph the equations of motion of two mobiles x 1 = 250-10t and x 2 = 15t and determine the time and the place of their meeting. (3 points)
2. The distance between two localities A and B is d = 50km. A mobile starts from A with speed v 1 = 20km / h, and al
the second mobile, with speed v 2 = 40km / h, starts from B, in the same direction as the first mobile, but at t 02 = 2h after
departure of the first mobile. The movements of the two mobiles are uniform rectilinear.
a) Write the laws of motion of the two mobiles, with respect to A.
b) Find the time and place of the meeting of the two mobiles, compared to A.

explanation:

physics means: "the branch of science concerned with the nature and properties of matter and energy. the subject matter of physics, distinguished from that of chemistry and biology, includes mechanics, heat, light and other radiation, sound, electricity, magnetism, and the structure of atoms."

it's when something is going so fast it makes a loud noise, breaking the sound barrier, for example: a jet makes a loud noise, not only cause of the jet but because they reached a point where they went so fast that you can year the noise from various parts, kinda like a police car, lets say the car was going   so fast that you hear the siren of the cop car right next to you, but the car is probably a mile a way, it's cos the siren was next to you a few seconds if you understand me
