mr. b has a hankering for jbc, as is common. he leaves his house and drives 5 miles 45 degrees northwest, 3 miles north, then 4 miles 15 degrees northwest to his closest wendys. determine his total displacement relative to his home.

i believe the answer is a

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.
