1. When Tiger Woods drives a 46 g golf ball, he tries to hit it at a maximum height of 30 m. What is the initial speed of the ball when he hits it off the tee if, at the top of its path, it is traveling at 77.17 m/s? 2. A roller coaster with a mass of 1,400 kg is being pulled up a hill by a force of 20,000 N along a distance of 6om. What is the speed of the roller coaster after it has fallen back down to the bottom of the hill (h=0 at the bottom)?

The pressure increases by 1.0 x 104 n/m^2 for every meter of depth beneath the surface of the ocean. at what depth does the volume of a pyrex (bulk modulus 2.6 x 1010n/m^2) glass cube, 9.8 x 10^−2m on an edge at the ocean's surface, decrease by 7.5 x 10−10m^3? explain the formula beyond this point: p=1.0x10^4, b=2.6x10^10, l=9.8x10^−2, delta v=7.5x10^−10. at some point l needs to be cubed. why p is divided by delta v?
