The practical domain of time is t ∈ [0, 4.25s].
- The set of values that make feel in a particular context is referred to as the sensible area.
- All feasible solutions are addressed by way of theoretical domains and stages.
- domain names and stages restrict the solution sets such that they may be realistic in the parameters given
- .The ball begins its motion at time t = 0s.
- To locate the time while the ball hits the floor,
- we solve the equation:
- h(t) = -16t² + 68t
- h(t) = 0
- -16t² + 68t = 0
- t(-16t + 68) = 0
- t = 0 and -16t + 68 = 0.
- 16t = 68
- t = 68/16
- t = 4.25
- h(t) is non-negative within the interval [0, 4.25].
- Hence, the practical domain is 0 ≤ t ≤ 4.25 s.
