False. Strontium 90 has a half life of only 30 years, and as millions of years pass, about the time fossils have been around, most if not all of any strontium would have decayed.
Acceleration of a body is defined as rate of chance in velocity with respect to time and its S.I. Units are
/ or 
Magnitude of average acceleration of a body = (final speed - initial speed)/time interval = 
where, final speed =v= 11 m/s; initial speed = u = 6 m/s; and time interval = t = 3 s
Hence acceleration =
