1.-Two particles moving in a straight line in a laboratory reference system at a speed v = 3/4c, hit a stationary target with a time interval t = 50 [ns]. Finding the proper distance between the particles before hitting the target.
2.-Certain particle moving with velocity v in a sitema O; its direction forms an angle μ with the axis X. To determine the corresponding angle in the system X´ which moves with velocity V over the system or in the positive direction of X axis if the X and X´ match.
3.-There is a triangle where the length of each one of its sides is equal to Lo. Calculate the perimeter of this triangle in a reference system moving with constant with V respect to the over:
a) one side;
b) one of its bisectors.
