A classic problem ( Problem 1003 ) asks for the initial velocity and height of a stone that returns to earth in 10 seconds. A stone is thrown vertically upward from the

Total distance: Find when ( v(t)=0 ): ( t^2 - 4t + 3 = 0 ) → ( (t-1)(t-3)=0 ) → ( t=1,3 ) : Differentiate the position function with respect to

For , we integrate or differentiate.

16 t sub 1 squared plus open bracket 248 open paren t sub 1 minus 2 close paren minus 16 open paren t sub 1 minus 2 close paren squared close bracket equals 1000 Solving this yields They pass at (or approx. 600 ft) above the ground 3. Constant Deceleration (The Train Problem)
