Question: 1. At time t in seconds, a particle's distance s(t), in micrometers (μm), from a point is given by s(t) = et - 1. What is the average velocity of the particle from t = 2 to t = 4?
2. At time t in seconds, a particle's distance s(t), in centimeters, from a point is given by s(t) = 4 + 3 sin t. What is the average velocity of the particle from t = π/3 to t = 7π/3?
