    Two spherical objects, both of mass m and radius R, have center-to-center separation 4R and are initially at rest. No external forces act. The spheres accelerate towards one another until they collide. (a) What is the speed of each object just before the collision? Find the exact answer using energy methods. (b) Using the final speed from part (a), and assuming the acceleration is roughly constant and equal to the initial acceleration, calculate an upper limit on the time it...

    Consider independent random samples from two populations that are normal or approximately normal, or the case in which both sample sizes are at least 30. Then, if σ1 and σ2 are unknown but we have reason to believe that σ1 = σ2, we can pool the standard deviations. Using sample sizes n1 and n2, the sample test statistic x1 − x2 has a Student's t distribution where t = x1 − x2 s 1 n1 + 1 n2 with degrees...
