Problem 91GP Pricey Stamp A rare 1918 Jenny stamp, depicting a misprinted, upside-down Curtiss JN-4 Jenny airplane, sold at auction for $525,000. A collector uses a simple magnifying glass to examine the Jenny, obtaining a linear magnification of 2.5 when the stamp is held 2.76 cm from the lens. What

A 0.620-kg wood block is firmly attached to a very light horizontal spring (k = 180 N/m) as shown in Fig. 8-35. This block-spring system, when compressed 5.0 cm and released, stretches out 2.3 cm beyond the equilibrium position before stopping and turning back. What is the coefficient of kinetic fric

Consider a grey squirrel falling out of a tree to the ground. (a) If we ignore air resistance in this case (only for the sake of this problem), determine a squirrel's velocity just before hitting the ground, assuming it fell from a height of 3.0 m. (b) If the squirrel stops in a distance of 2.0 cm th
