If something at rest is accelerating at 9.8 m/s^2, how long in seconds will it take to reach 10% of c? Answer to the nearest order of magnitude - will it take approximately 1000, 10k, 100k, 1000k seconds?

I’m sure you know this is an exponential growth question but have no intuition of the answer.

That is a linear growth problem whose answer is very easy to intuit.

You must be joking. A high schooler with a few hours of physics classes can intuit the answer.
