1. A container containing 2 L of a gas is collected at 50 K and then allowed to expand to 20.0 L. What must the new temperature be in order to maintain the same pressure? Only use your number keys to answer. 2. A sample of carbon dioxide is stored in a closed container at 0.50 atm and 300 K. The container is then heated to 600 K. Assuming the volume remains constant, the new pressure is atm. Only use your number keys to type your answer

You throw a small rock straight up from the edge of a highway bridge that crosses a river. the rock passes you on its way down, 7.00 s after it was thrown. what is the speed of the rock just before it reaches the water 28.0 m below the point where the rock left your hand? ignore air resistance.

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
