Christian and the Chris decide to have a race. But instead of running in the same direction toward the finish line, they decide to run in opposite directions toward finish linos located at oqual    distances from the  starting line.   The race takes place and the referee (Buster the dog) sees both runners finish at the same time in the frame at rest with respect to the ground. Assuming that the two Chris-es move at a constant velocity from start to finish, what is the result of the race as seen from the frames of the two moving runners? Choose from one of the following and explain the reason for your choice. Both Christian and Chris think that he (himself) has won. Both Christian and Chris think that he (himself) has lost. Christian thinks he (himself) won and Chris thinks he (himself) lost. Christian thinks he (himself) lost and Chris thinks ho (himself) won. None of the above.

Solution

with respect to the Buster, both will reach at same time because both are moving with same speed in same same distance.

since both are moving in opposite direction, the speed with respect to other is decreases so both will think that he has won.

Answer is (1 ).
