A catapult on a cliff launches a large round rock towards a ship on the ocean below. The rock leaves the catapult from a height H = 31.0 m above sea level, directed at an angle theta = 49.1° above the horizontal, and with a speed v = 26,8 m/s. Assuming that air friction can be neglected, calculate the horizontal distance D traveled by the projectile.
i keep getting 64.03 or 40.26 and they both are wrong. Could somebody please help?

Find a formula for a function that has vertical asymptotes x = 2 and x = 7 and horizontal asymptote y = 2.
i Think its, f(x) something/(x-2)(x-7) or something/(x^2-9x+14)
i've tried putting x^2/(x-2)(x-7) but its wrong

5 AnswersPhysics9 years agoWrite nuclear equations to represent this process:?
A breeder nuclear reactor is a reactor in which nonfissile U-238 is converted into fissile Pu-239. The process involves bombardment of U -238 by neutrons to form U-239 which then undergoes two sequential beta decays.
Write nuclear equations to represent this process.

Is is b/c enzymes need to be at certain temp for it work? temp, and ph levels effect them. also higher temp denatures things..Thats all i got. I need some help with better way of explaining it
