Ollie Oksenfrei's acceleration at t = 3s is measured to be what magnitude and direction?

To determine the magnitude and direction of Ollie Oksenfrei's acceleration at t = 3 seconds, it's essential to analyze the components of his motion. The value of 2.12 m/s indicates the rate of change of velocity over time, and the direction of 81.87 degrees specifies the angle at which this acceleration is applied relative to a defined reference, such as the horizontal axis.

In projectile motion or any two-dimensional motion analysis, acceleration can typically be broken down into horizontal and vertical components. The angle given, 81.87 degrees, suggests that the acceleration vector is largely vertical, indicating a significant vertical acceleration component compared to the horizontal one. Such angles can arise in scenarios involving objects being thrown or acted upon by forces that have a vertical nature—like gravity or specific propulsion forces.

This combination of magnitude and direction effectively describes Ollie's acceleration at a given moment, encapsulating both how fast he is accelerating and the direction in which that acceleration occurs. Thus, the choice providing 2.12 m/s in magnitude and 81.87 degrees in direction aptly represents the conditions of Ollie’s motion at the specified time.
