I've been trying to solve this problem: Given a particle with mass m, initial position (0,0,0), and initial velocity , find equations for the particle's position and velocity if the force acting on it is . I've figured out that since there is no x or z acceleration, the velocity in those directions will be constant, so all I need to find is velocity in the y direction, . From F=ma I know the acceleration in y: My first thought was just to integrate both sides with respect to t, but I can't figure out how to integrate the y term on the right side. Any suggestions? — jwillbur 16:24, 9 September 2008 (UTC)
Q. What is the target population? What property a representative sample is expected to hold? —Preceding unsigned comment added by 89.108.14.159 ( talk) 17:51, 9 September 2008 (UTC)
What are index number and their uses in business? —Preceding unsigned comment added by 89.108.14.159 ( talk) 17:53, 9 September 2008 (UTC)
Argue that descriptve statistics and inferential statistics are must for each other.
Explain the difference between population and statistical population? —Preceding
