As a prank, your friends have kidnapped you in your sleep, and transported you out onto the ice covering a local pond. since you're an engineer, the first thing you do when you wake up is drill a small hole in the ice and estimate the ice to be 6.7cm thick and the distance to the closest shore to be 31.7 m. the ice is so slippery (i. e. frictionless) that you cannot seem to get yourself moving. you realize that you can use newton's third law to your advantage, and choose to throw the heaviest thing you have, one boot, in order to get yourself moving. take your weight to be 634 n. (lucky for you that, as an engineer, you sleep with your knife in your pocket and your boots on.)a. if you throw your 1.32-kg boot with an average force of 457 n, and the throw takes 0.646 s (the time interval over which you apply the force), what is the magnitude of the force that the boot exerts on you? (assume constant acceleration.)b. how long does it take you to reach shore, including the short time in which you were throwing the boot?

The lights used by mark watley (played by matt damon) during the film the martian seem to be metal halide lamps. metal halide lamps are filled with vaporized mercury and metal-halogen compounds. when an electric current is passed through the lamp, the tube begins to glow a bright white/blue color. if you were to pass this light through a prism to separate the individual light frequencies, you would see a rainbow just as you would if using natural sunlight because of the complexity of the metal halide gas and the vast amount of possible electron transitions. (the study of light in this way is known as spectroscopy and allows astronomers to know exactly what atoms compose distant stars, simply by looking at the light they emit. the spectral lines an atom produces uniquely identifies that atom just like a fingerprint uniquely identifies a person. the momentum equation and energy equation that we have used above can be combined to give the following equation: c = e p where again p is the phonon momentum, e is the photon energy and c is the speed of light. when you divide the photon energy found in #6 by the photon momentum found in #4, do you get the speed of light? (if not, check your work for questions #4 through #6). yes no

An important dimensionless parameter concerned with very high-speed flow is the mach number, defined as v/c, where v is the speed of the object such as an airplane or projectile, and c is the speed of sound in the fluid surrounding the object. for a projectile traveling at 1170 mph through air at 50 ˚f and standard atmospheric pressure, what is the value of the mach number?
