## Calculating the Height of the Ball Fired from the Launcher

When a ball is fired from a launcher with an initial velocity of 20 m/s and travels a horizontal distance of 9m away from the base, we can calculate its height using the equations of motion. Let's break down the steps:

## Step 1: Calculate the Time Taken

First, we need to calculate the time it takes for the ball to reach the maximum height. Since the ball is fired horizontally, the initial vertical velocity is 0. The time it takes to reach the horizontal distance of 9m is the same as the time to reach the maximum height.

## Step 2: Use the Formula to Find Height

Next, we can use the formula: h = ut + (1/2)gt², where h is the height, u is the initial vertical velocity (0 m/s in this case), g is the acceleration due to gravity, and t is the time taken. By plugging in the values, we can calculate the height of the ball.

## Final Answer: The height of the ball can be calculated using the equations of motion and the given initial velocity and horizontal distance. Understanding the steps involved in the calculation helps in determining the height accurately.

**Calculating the height of a ball fired from a launcher involves considering the initial velocity, horizontal distance traveled, and the equations of motion. By following the steps outlined above, we can accurately determine the height of the ball. It's important to understand the concepts of motion and apply them correctly to solve such problems efficiently.**

When dealing with projectile motion, the initial velocity, angle of projection, and gravitational acceleration play crucial roles in determining the trajectory of the object. By focusing on the vertical and horizontal components of motion separately, we can simplify the calculations and arrive at the correct height of the ball.

Remember to pay attention to the given data, identify the key variables, and apply the relevant equations to solve the problem effectively. Practice solving similar problems to enhance your understanding of projectile motion and improve your problem-solving skills.
