Question
Solve the following problem
a) Find the velocity of the bird relative to earth
b) Find the total distance flown by the bird before the trains meet.
![Trains A and B approach each other. Each train moves at
constant velocity 50 miles/hr relative to the earth. A bird flies
back and forth from A to B, reversing instantly at each train, and flying at constant speed relative to the
earth. At time t= 0, the bird leaves A, and A and B are 100 miles apart. The time required for the bird
A
B
to make its first round trip is 0.5 hours.
