Question

A plane flying horizontally above Earth’s surface at 89 m/s drops a crate. The crate strikes the ground 30.0 seconds later. What is the magnitude of the horizontal component of the crate’s velocity just before it strikes the ground?

A. 2670 m/s
B. 89 m/s
C. 2700 m/s
D. 0 m/s

Answer 1

The magnitude of the horizontal component of the crate's velocity just before it strikes the ground is 89 m/s.

Step-by-step explanation:

To find the magnitude of the horizontal component of the crate's velocity just before it strikes the ground, we need to consider the horizontal motion of the plane.

Since the plane is flying horizontally above the Earth's surface, the horizontal component of its velocity remains constant. Therefore, the magnitude of the horizontal component of the crate's velocity just before it strikes the ground is equal to the horizontal component of the plane's velocity.

The given information states that the plane is flying horizontally at a speed of 89 m/s, so the magnitude of the horizontal component of the crate's velocity just before it strikes the ground is also 89 m/s.
