A 75-kg snowboarder has an initial velocity of 5.0 m/ s at the top of a 28° incline. After sliding down the 110-m long incline (on which the coefficient of kinetic -
friction is =0.18), the snowboarder has attained a velocity v. The snowboarder then
slides along a flat surface at the bottom of the slope (on which kinetic-friction is 0.15) and comes to rest after a distance "x".
• Use Newton’s second law to find the snowboarder’s acceleration while on the incline
and while on the flat surface.
• Then use these accelerations to determine x. A+ for shown work, thanks:)

Calculate the ratio of h+ ions to oh– ions at a ph = 6. find the concentration of h+ ions to oh– ions listed in table b of your student guide. then divide the h+ concentration by the oh– concentration. record this calculated ratio in table a of your student guide. compare your approximated and calculated ratios of h+ ions to oh– ions at a ph = 6. are they the same? why or why not? record your explanation in table a. what is the concentration of h+ ions at a ph = 6? mol/l what is the concentration of oh– ions at a ph = 6? mol/l what is the ratio of h+ ions to oh– ions at a ph = 6? : 1

Atypical jetliner lands at a speed of 146 mi/h and decelerates at the rate of (10.4 mi/h)/s. if the jetliner travels at a constant speed of 146 mi/h for 1.5 s after landing before applying the brakes, what is the total displacement of the jetliner between touchdown on the runway and coming to rest?
