Out of "Aplicative Mathematics" Question #24:

A launches an object. The Coordinates of the launch site is (34,22,0,0) (x,y,altitude,time). The object is sighted 4 time units later at (54,40,16,4). Disregard air resistance. Assume that gravitational acceleration(9.8m/s^2) is equal regardless of altitude. Where will the object land? Use coordinates to answer. If needed, round to the first decimal. You may use a calculator if you wish.

a) When thrust (acceleration) is cut at point of launch:

b)When thrust is cut at 4 time units after launch:

c) When thrust is cut at 10 time units after launch:

d) What is the initial speed, if thrust is cut at point of launch?:

Bonus) What is the angle of launch? If needed, round to the first decimal.


I think I've got the question translated right. I think you're supposed to regard altitude as in meters (edit: Or kilometers. Try that.)... and time units as in seconds.


Have fun :p
