Question

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

Explanation:

Step1: Recall the orbital speed requirement

The minimum speed for an object to go into orbit around Earth is about \(7900\ m/s\). Objects with speeds less than this will fall back to Earth.

Step2: Analyze each object's speed

• Object \(W\): \(6799\ m/s<7900\ m/s\), so it will not go into orbit.
• Object \(X\): \(3562\ m/s<7900\ m/s\), so it will not go into orbit.
• Object \(Y\): \(8105\ m/s > 7900\ m/s\), so it can go into orbit.
• Object \(Z\): \(9324\ m/s>7900\ m/s\), so it can go into orbit.

Answer:

Y and Z
