2.) A small rocket is fired from a launch pad 10 m above the ground. This initial position can be modelled by = <0,0, 10 >. The initial velocity of the rocket is given by v, = < 50,0, 30 > m/s. A crosswind = < 0,2.5, -9.8 > describes the %3D blowing to the north produces an acceleration of 2.5 m/s2. If a(t) acceleration of the rocket, determine the velocity function, v(t), and the position function, r(t) for the rocket. How long after launch does the rocket hit the ground? Round to the nearest second. %3D

Domain

In simple mathematics terms, a domain is defined as the space on which all the possible inputs for the function will lie. It can also be expressed as a set of departures for the required function.
