Question

The chart shows the speeds at which four objects are launched into the air.

A 2 column table with 4 rows. The first column is labeled Object with entries W, X, Y, Z. The second column is labeled Speed (meters per second) with entries 6799, 3562, 8105, 9324.
Based only on the information in the chart, which objects will most likely go into orbit around Earth?

W and Y
X and Y
Y and Z
W and Z

Answer 1

Y and Z

Their speeds (8105 m/s and 9324 m/s) exceed the approximate low-Earth orbital speed (~7.9 km/s), so they would most likely go into orbit.
