A plane flying horizontally at a speed of 50 m/s and at an elevation of 160 m drops a package,and 2.0 s later it drops a second package.How far apart will the two packages land on the ground if air resistance is negligible?
A)100 m
B)160 m
C)180 m
D)320 m

Question

Quizplus · Accepted Answer

The horizontal distance between the two packages is determined by the horizontal speed of the plane and the time interval between the drops. The plane travels 50 m/s * 2 s = 100 m horizontally in 2 seconds, so the packages will land 100 m apart.
