How far is the post driven in on each stroke
A pile driver drives a post into the ground. The mass of the pile driver is 3,500 kg and it is dropped through a height of 8.0 m on each stroke. If the resisting force of the ground is 4.5 × 106 N, how far is the post driven in on each stroke?

A solid cylinder has a mass of 5kg, a diameter of 9cm and is 60cm high. it starts at point A and must be moving at 2m/s so it slides on to a convyer belt (moving at 2m/s) at point D.
If data containing two variables X and Y (with X as the only predictor variable for Y) were standardized, the slope of a best-fit regression line would equal:
The correlation (r) between these two variables is 0.67. The variances of x and y, respectively, are 14.57 and 8.16. The means of x and y are 20.00 and 9.31. What is the intercept of the regression line the researchers used?
