Projectile Motion Calculation: A Reflective Analysis

What value is Rosa most likely trying to find?

A. the vertical acceleration of a projectile launched at an angle

B. the horizontal displacement of a projectile launched at an angle

C. the horizontal component acceleration of a projectile launched at an angle

Answer:

C - the horizontal component acceleration of a projectile launched at an angle

Reflecting on the data provided, Rosa uses the formula (vi cos)t to calculate the horizontal component acceleration of a projectile launched at an angle. This calculation involves understanding the speed at which the projectile moves horizontally (vix) and the time (t) it has been moving horizontally.

The horizontal displacement of a projectile is only influenced by the horizontal speed and time. As the angle of launch is increased from 0 degrees to 45 degrees, the range or horizontal displacement also increases, reaching a maximum at 45 degrees. However, if the angle goes beyond 45 degrees, the horizontal displacement starts to decrease.

By focusing on the horizontal component acceleration, Rosa is able to determine the factors that affect the projectile's motion in the horizontal direction. This reflective analysis enhances understanding of projectile motion calculations and the relationship between angle of launch and horizontal displacement.
