With a cruising speed of 2.30 x 10³ km/h, the French supersonic passenger jet Concorde is the fastest commercial airplane. Suppose the landing speed of the Concorde is 20.0% of the cruising speed. If the plane accelerates at -5.80 m/s², how far does it travel between the time it lands and the time it comes to a complete stop. i dont understand how to do this one

Let the sample size of leg strengths be 7 and the sample mean and sample standard deviation be 945 watts and 48 watts, respectively. (a) is there evidence that leg strength exceeds 900 watts at significance level 0.05? find the p-value.there is , evidence that the leg strength exceeds 900 watts at ? -0.05. 0.001 < p-value 0.005 0.05 p-value < 0.10 0.10 p-value < 0.25 o 0.010 p-value 0.025 (b) compute the power of the test if the true strength is 915 watts. (c) what sample size would be required to detect a true mean of 915 watts if the power of the test should be at least 0.9? n= exact number, no tolerance
