The function s = f(t) gives the position of a body moving on a coordinate line, with s in meters and t in seconds. S = 8t - t2. Ost= 8 Find the body's speed and acceleration at the end of the time interval. 8 m/sec, - 2 m/sec2 B 8 m/sec, -16 m/sec2 -8 m/sec, - 2 m/sec2 24 m/sec, -16 m/sec2 E -8 m/sec, -16 m/sec2
