need show work and interpretation along with values in table.

A model rocket s launched with an initial velocity of 11 feet per second from the height of lal feet. 16t 11 [c]t lal models the path of the rocket where trepresents s (t) The function the time, in seconds, after which the rocket is launched and s represents the height of the rocket at time t. Note: if lal 3 and [cl 7, then s(t) 16t2 117t 3 1. Eu in the table of values for the function, and give a short interpretation for each point. 2.
