If an object-spring system is hung vertically and set into oscillation, why does the motion eventually stop?

Which statement is true about the atoms in helium gas? A. They have strong attractions to one another. B. They are not closely packed. C. They are arranged in an orderly pattern. D. They travel in circular paths.

A fellow student of mathematical bent tells you that the wave function of a traveling wave on a thin rope is y (x, t) = 2.30mmcos[ (6.98rad/m) x + (742rad/s) t]. Being more practical-minded, you measure the rope to have a length of 1.

Suppose s (t) is the position of an object moving along a line at time t is greater than or equal to 0. What is the average velocity between the times t=a and t=b? What is the instantaneous velocity at t=a?

Estimate how long it would take one person to mow a football field using an ordinary home lawn mower. suppose that the mower moves with a 1-km/h speed, has a 0.5-m width, and a field is 360 ft long and 160 ft wide. 1 m = 3.281 ft.
