A sports car accelerates from rest to 98 km/hr in 18 s. What is its average acceleration in m/s^2?NOTE: Do NOT include units in your answer, just type in the number value! What I did was immediately make 98 km into 98000 meters. I then took 98000 and divided it by 60 twice (once would make it m/minute, again to make it m/second) and got 27.222222. I took this final answer, divided it by 18 seconds, got 1.512345679, and changed it to 1.5 taking significant figures into account. So would my final answer of 1.5 m/s^2 be correct?
