Algebra
A turbo-jet flies 50 mph faster than a super-prop plane. If a turbo-jet goes 2000 miles in 3 hours less time than it takes the super-prop to go 2800 miles, find the speed of each plane. I do not understand how to do this at all. Please explain as well as you can! Thanks.

physics
A Cessna aircraft has a lift-off speed of 120 km/h. (a)What minimum constant acceleration does this require if the aircraft is to be airborne after a take=off of 240m? Work: 120 km/h-->33.3 m/s (33.3 m/s)^2= (16.7 m/s)^2 + 2a(240 m) a= 1.73 m/s^2 [What did I do wrong?] (b)...

Application prob. for Trig.
Hi, A fountain in a shopping centre has a single jet of water. The height of the jet of water varies according to a sinusoidal function. A student notes that, in exactly one minute, the jet goes from a minimum height of 2m to a maximum height of 6m and back to 2m. At 13:00, ...
