Thank you for the response, but in reference to sig figs, isn't 38 divided by 4.5 = 8.4? Since they both have 2 significant figures. Argh, this should be the easy part of physics but I find myself getting easily confused :-p
Oh okay, thank you. I did not know that my answer is supposed to have the same number of significant figures as the number with the most sig figs in the question. So I work it out to as many decimal places as I can, then cut it down to the number with the most sig figs? In future cases, does...
Hi, I don't know what I'm doing wrong but these significant figures seem to be screwing me up.
Problem:
A bike rider accelerates constantly to a velocity of 7.5 m/s during 4.5 s. The bike's displacement is +19 m. What was the initial velocity of the bike?
The textbook says the answer is 0.94...
