1. Calculate the average velocity between (A& B) and (C&D) 2. Explain why the distance covered by the car and the duration are proportional.
3. Write the mathematical relation of the distance as a function of the duratio

Atank holds 1000 gallons of water, which drains from the bottom of the tank in half an hour. the values in the table show the volume v of water remaining in the tank (in gallons) after t minutes. t(min) 5 10 15 20 25 30v(gal) 694 444 250 111 28 0(a) if p is the point (15, 250) on the graph of v, find the slopes of the secant lines pq when q is the point on the graph with t = 5, 10, 20, 25, and 30.(b) estimate the slope of the tangent line at p by averaging the slopes of two secant lines.(c) use a graph of the function to estimate the slope of the tangent line at p. (this slope represents the rate at which the water is flowing from the tank after 15 minutes.)show all steps.

Using the work energy theorem. what is the velocity of a 850kg car after starting at rest when 13,000j of work is done to it.
