Projectile Motion Calculations

The video tutorial explains how to calculate catapult launch parameters, focusing on determining horizontal and vertical distances, velocities, and the time to reach the apex. It uses physics equations to solve for these variables, providing a detailed example calculation. The tutorial emphasizes the importance of the 45-degree launch angle for maximum distance and concludes with a summary of the findings.

What is the primary purpose of measuring displacement and time in catapult calculations?

• To determine the color of the catapult

• To measure the weight of the projectile

• To calculate the launch angle

• To find the velocity and height

In the example scenario, what is the significance of firing the catapult at 45 degrees?

• It increases the projectile's weight

• It minimizes the flight time

• It maximizes the distance

• It reduces air resistance

Which equation is used to calculate the vertical distance in projectile motion?

• Energy = mass * speed of light^2

• Force = mass * acceleration

• Velocity X = distance X / time

• Delta y = initial velocity y * time + 1/2 * gravity * time^2

How is the time to reach the apex of the projectile's path determined?

• It is the total time multiplied by two

• It is the total time divided by two

• It is the total time divided by three

• It is the total time minus one second

What is the initial velocity in the Y direction when calculating the distance Y?

• It is equal to the final velocity

• It is zero

• It is equal to the velocity X

• It is equal to the displacement

What does the final calculation verify about the launch angle?

• It is more than 90 degrees

• It is 45 degrees, the perfect launch angle

• It is exactly 60 degrees

• It is less than 30 degrees
