2023 HESI A2 PHYSICS EXAM PREP Q&A 1. 1. QUESTION Suppose the final velocity of a motorcycle is 26 m/s east, and it has an average velocity of 76 m/s east. What is the initial velocity of the motorcycle? Assume that the east direction is the positive direction of motion. o -152 m/s o 126 m/s o -126 m/s o 152 m/s We know the average velocity is half the sum of the initial and final velocities. However, this question asks us for the initial velocity. Step 1: Rearrange the average veloci...
