Points: 0.27 of 1 Save Na The height, h (in feet) of a model rocket launched from the roof of a a. Expand s(t) = - 16(t + 1)(t -3) to write it in the form DU building at t seconds is given by s(t) = at + bt + c. h =s(t) = - 16(t + 1)(t -3). La s(t) = - 161 + 32t+ 48 Ah=s(t) CU b. What is the height of the rocket at t = 0? The inital height is 48 feet. te At c. Find the formula for the velocity s'(t). s'(t) = -32t + 32 ntro d. What is the initial velocity? s'(0) = ft per sec.
