Aroller coaster starts at the top of a straight track that is inclined at 30degrees with the horizontal. this causes it to accelerate at a rate of 4.9m/s^2(1/2g).

a. what is the roller coaster's speed after 3 seconds?
b. how far does it travel during that time? ### Other questions on the subject: Physics Physics, 22.06.2019 01:30, markmeinberg

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 If jerome is swinging on a rope and transferring energy from gravitational potential energy to kinetic energy, is being done.
