A-1: A 1.9-kg piece of wood from a sunken pirate ship has a volume of 2.16 X 10 3 m3. Will this piece of wood float to the surface of the water or remain submerged with the ship? A-2: Ursula drops a 0.0330-kg ice cube into her glass of soda water. The ice cube has dimensions of 3.0 cm X 3.0 cm X 4.0 cm. Does the ice cube float or sink in Ursula's drink? A-3: Which is more dense, a 20.0-g silver bullet that occupies a volume of 1.9 cm3, or the 5.98 X 1024-kg Earth, that occupies a volume of 1.08 x 1021 m3? A-4: In her gymnastics routine, Regina dismounts from the uneven-parallel bars and lands straight-legged on the ground, compressing her 0.250-m-long femur by 2.10 X 10-5 m. If the femur has a cross-sectional area of 3.00 X 10- m2 and the stress modulus of bone is 2.00 x 1010 N/m2, with how much force does Regina hit the ground? A-5: When they go swimming in their favorite water hole, Jeb and Dixie like to swing over the water on an old tire attached to a tree branch with a 3.0-m nylon rope. If the diameter of the rope is 2.00 cm, by how much does the rope stretch when 60.0-kg Dixie swings from it? (Ynylon = 3.7 x 109 N/m2)
