1. The problem statement, all variables and given/known data Giancoli 5th edition chapter 3 problem 38 a rescue plane wants to drop supplies to isolated mountain climbers on a rocky ridge 235m below the plane is traveling horizontally with a speed of 69.4m/s b) supposes, instead that the plane releases the supplies a horizontal distance of 425m in advance of the moutain climbers. What vertical velocity should the supplies be given so that they arrive precisely at the climbers position? 3. The attempt at a solution I attempted it several times using two different method the second time was using [tex] X = V_0 t [/tex] t= 6.12s so then [tex] y =y_0 + V_0t + 1/2 a_y (t^2) [/tex] answer was 8.41m/s but then my question is that for my first attempt at this question I try to figure out the angle if they threw it upward or downward but why does that angle not matter for the vertical or horizontal velocity?
