A kind-hearted rich person wants to counteract global warming by releasing giant ice cubes into the ocean. A massive cube of ice (917 kg/m^3) measuring 32 meters on a side is suspended by a steel cable from a helicopter. The helicopter lowers the cube so that the bottom 8 meters is underneath the surface of the salt water (1,026 kg/m^3). As the helicopter hovers at this height, determine the tension in the cable. Determine the acceleration of the ice cube at the moment the steel cable is severed. As it falls into the ocean, the ice cube's momentum carries it completely underwater. Determine the acceleration of the cube at this moment.

The owner of a company that manufactures drinking cups decides it would be impressive to build an inground swimming pool that is a scaled up version of her best selling cup. For this particular cup, the area of the circular opening at the top is 1.24 times the area of the circular bottom. Her pool contractor informs her that when the pool is full of water, the magnitude of the force acting on the top surface will be the same as the magnitude of the force acting on the bottom surface. Determine the depth of the pool. m

common belief is that a hole in a jet plane can suck a person out. On an episode of a popular TV series, the hosts attempted to determine whether this is possible. According to the hosts' experiment, such an event cannot happen. Did they need to perform the experiment? As a science adviser to the show, the hosts ask you to perform a crude calculation to test the myth. A typical jet plane travels at 532 mph at a cruising altitude of 30500 ft. The windows on a jet plane measure 14.0 in × 14.0 in. Calculate the force ? exerted on such a window as the plane flies at 30500 ft above the sea level. Assume the density and pressure of air at 30500 ft are 0.452 kg/m3 and 292 mbar, respectively, but that the interior of the plane remains pressurized to atmospheric pressure, 1 atm. Calculate the fractional difference between this force and the weight ?man of a typical adult male (185 lb). How would you respond to Adam and Jaime? a)There is no need to perform the…

At one point in time, the price of gold was about $1400 per ounce, while that of silver was about $20 an ounce. The "ounce" in this case is the troy ounce, which is equal to 31.1035 g. (The more familiar avoirdupois ounce is equal to 28.35 g.) The density of gold is 19.3 g/cm^3 and that of silver is 10.5 g/cm^3. a)If you found a spherical gold nugget worth $5.00 million, what would be its diameter? b)How much would a silver nugget of that size be worth?
