To find the average velocity of an arrow shot upwards at 50 m/s, the height function is given by h=50t-0.36t^2. The average velocity over the interval [1, 1.03] can be calculated using the formula for average rate of change, which involves evaluating the height at both endpoints and finding the difference. Specifically, this involves computing h(1) and h(1.03) to determine the average rate of change over the specified interval. The discussion confirms that this is a secant problem rather than calculating the average value of the function. The final average velocity result should be expressed to four decimal places.
