Calculating Average Speed of a Baseball in Horizontal Projectile Motion

In summary, horizontal projectile motion is the motion of an object that is launched horizontally and moves in a straight line under the influence of gravity. The two main factors that affect it are the initial velocity and the force of gravity. It can be calculated using equations for both horizontal and vertical distances, and its trajectory is a parabola. Common real-life examples include throwing a ball, shooting a projectile, and launching a rocket.

This is the problem word for word:
A student throws a baseball at a large gong
48 m away and hears the sound of the gong
1.18893 s later. The speed of sound in air is
330 m/s.
What was the average speed of the baseball on its way to the gong? (For simplicity,
assume its trajectory to be a straight line.)
Answer in units of m/s.

I don't need the answer. I'd really just like to be pointed in the right direction.
Thanks so much.

The first thing to do is to write down the relevant kinematic equations.
 

1. What is horizontal projectile motion?

Horizontal projectile motion is the motion of an object that is launched horizontally and moves in a straight line under the influence of gravity. This type of motion is also known as uniform motion, as the object moves at a constant horizontal velocity while its vertical velocity changes due to gravity.

2. What factors affect horizontal projectile motion?

The two main factors that affect horizontal projectile motion are the initial velocity of the object and the force of gravity. The initial velocity determines the speed and direction of the object, while the force of gravity causes the object to accelerate towards the ground.

3. How is horizontal projectile motion calculated?

The horizontal distance traveled by an object in projectile motion can be calculated using the equation d = vt, where d is the distance, v is the initial velocity, and t is the time. The vertical distance can be calculated using the equation d = ½gt², where g is the acceleration due to gravity and t is the time.

4. What is the trajectory of an object in horizontal projectile motion?

The trajectory of an object in horizontal projectile motion is a parabola. This means that the object will travel in a curved path, with the highest point being the point of maximum height and the lowest point being the point of impact on the ground.

5. What are some real-life examples of horizontal projectile motion?

Some common examples of horizontal projectile motion include throwing a ball, shooting a projectile from a cannon, or launching a rocket into space. These all involve a horizontal initial velocity and the force of gravity causing the object to follow a parabolic path.
