A man goes fishing for dinner. He walks 5 km due West from his house, and tries to catch a fish, after 4 hours and no fish, he walks 5 km due North. At the new location, he quickly catches a fish. He walks 5 km due South and arrives at home. On the way home, he saw a bear. What is the color of the bear?

it has to be b, about 97 percent.

when two balls of the different masses are dropped from equal height, they reach the ground at the same time .this is because they experience the same acceleration.

the acceleration is independent of mass.

thus when they are dropped they will always maintain the same velocity and travel the same distance (neglect air resistance of course) at the same time.
