Problem 75P A 0.500-kg block, attached to a spring with length 0.60 m and force constant 40.0 N/m, is at rest with the back of the block at point A on a frictionless, horizontal air table (Fig. P7.69). The mass of the spring is negligible. You move the block to the right

Consider a mass m constrained to move on the x axis and subject to a net force F = kx where k is a positive constant. The mass is released from rest at x = x0 at time t = 0. Use the result (2.85) in Problem 2.12 to find the mass's speed as a function of x; that is, dx I dt = g(x) for some function g(

Concepts of Biology 1
What is the main difference between dispersal and vicariance? a. One leads to allopatric speciation, whereas the other leads to sympatric speciation. b. One involves the movement of the organism, whereas the other involves a change in the environment. c. One depends on a genetic mutation occurring, w

Heli-Segways for Workers Consider a region with 6 million workers and two cities (A and B), each with an initial workforce of 3 million (the utility-maximizing workforce). Suppose the heli-segway (a fl ying personal transporter) replaces the automobile, cutting commuting cost and increasing the utili
