Question

An object falls for 2.3 s, from what height does it fall? Use 10m/s² for g. Round answer to 3 significant figures.

Answer 1

The object fell from a height of approximately 26.45 meters.

Step-by-step explanation:

To determine the height from which the object fell, we can use the equation h = 1/2 * g * t^2, where h is the height, g is the acceleration due to gravity (10 m/s^2), and t is the time taken to fall (2.3 s).

Substituting the given values into the equation, we have h = 1/2 * 10 * (2.3)^2 = 26.45 m. Therefore, the object fell from a height of approximately 26.45 meters.

Key points:

• Use the equation h = 1/2 * g * t^2 to calculate the height.
• Substitute the given values: g = 10 m/s^2 and t = 2.3 s.
• Calculate h = 1/2 * 10 * (2.3)^2 = 26.45 m.
