Planet X has three times the free-fall acceleration of Earth. a. A ball is thrown vertically upward with the same initial velocity on Earth and on X. How does the maximum height reached by the ball on X compare to the maximum height on Earth? Justify your answer with both words and kinematics calculations. Your answer should state "The ball goes times higher on X."
b. Now, a ball is thrown vertically upward on X with three times the initial velocity of an identical ball on earth. How does the maximum height reached by the ball on X compare to the maximum height on Earth? Justify your answer with both words and kinematics calculations. Your answer should state "The ball goes times higher on X."

The chart shows the costs and shipping times for materials that a company needs to build a new product. which describes the best trade-off if the company needs to start building their product within the next two years? they should order the domestic materials because it is always best to choose the fastest shipping time. they should order the imported materials because it is always best to choose the lowest cost for materials. since the shipping time is longer, they should order the domestic materials because the additional cost is worth it to get the materials in time. even though the shipping time is longer, they should order the imported materials because they are less expensive and should arrive in plenty of time to build the product.
