A science project produces unexpected results, and the results do not support the hypothesis. A student reviews the experiment and discovers that his lab group measured one of the chemicals in the experiment incorrectly. What should the student do? A. report the results and not worry about the mistake

B. change the conclusion to support the hypothesis

C. repeat the experiment

D. assume that the conclusion would have supported the hypothesis anyway, even if the group did not made a mistake

Asilver dollar is dropped from the top of a building that is 1324 feet tall. use the position function below for free-falling objects. s(t) = −16t2 + v0t + s0 (a) determine the position and velocity functions for the coin. s(t) = v(t) = (b) determine the average velocity on the interval [1, 2]. ft/s (c) find the instantaneous velocities when t = 1 second and t = 2 seconds. v(1) = ft/s v(2) = ft/s (d) find the time required for the coin to reach the ground level. (round your answer to three decimal places.) t = s (e) find the velocity of the coin at impact. (round your answer to three decimal places.) ft/s
