Inch, an inchworm, is inching along a cotton clothesline. The 5 meter long clothesline has a mass of 0.2 kilograms, and is pulled tight under 100 N of tension. Vivian is hanging up her swimsuit 0 meters from one end when she sees Inch 2.54 cm (one inch) from the opposite end. She plucks the clothesline sending a terrifying 3 centimeter high wave pulse toward Inchy. If Inchy crawls at 1 inch per second, will he get to the end of the clothesline before the pulse reaches him

If the speed of a particle triples ,by what factor does its kinetic energy increase?

In a stagnant pool of water, a crayfish may spend much of its time lying with one side of its carapace near the surface of the water. in this position, it will move the walking legs on that side in a rhythmic back-and-forth motion. explain the likely function of this behavior.

Review multiple-concept example 7 in this chapter as an aid in solving this problem. in a fast-pitch softball game the pitcher is impressive to watch, as she delivers a pitch by rapidly whirling her arm around so that the ball in her hand moves in a circle. in one instance, the radius of the circle is 0.626 m. at one point on this circle, the ball has an angular acceleration of 66.1 rad/s2 and an angular speed of 12.6 rad/s. (a) find the magnitude of the total acceleration (centripetal plus tangential) of the ball. (b) determine the angle of the total acceleration relative to the radial direction.
