# The Exciting Physics of Free Fall Motion

## How fast is the ball going in m/s just before it strikes the ground?

A 3.00kg ball is thrown off the top of a 4.08m tall building with a speed of 9m/s. What is the final speed of the ball just before it hits the ground?

## Final Answer

We can calculate the final speed of the ball just before it hits the ground by using the equation of motion.

The equation involves the initial velocity, acceleration due to gravity, and the height from which the ball is thrown.

Inserting the values given in the problem statement will yield the required final velocity.

The question provided involves a classic physics problem related to free fall motion.

When an object is thrown from a certain height with a specific initial velocity, we can determine its final speed just before it hits the ground.

In this case, the ball is thrown with a speed of 9m/s from a 4.08m tall building.

To calculate the final speed, we need to consider the initial velocity and the acceleration due to gravity, which is approximately 9.8m/s².

Using the equation v² = u² + 2gs, where v is the final velocity, u is the initial velocity, g is the acceleration due to gravity, and s is the distance, we can find the final speed of the ball.

Substituting the values into the equation, we can solve for the final speed of the ball just before it strikes the ground.
