i’m confused on how to calculate this. i’m getting a negative value but don’t know if i should put the answer in as negative or disregard it and put the positive value
In SI units, speeds are measured in meters per second (m/s). But, depending on where you live, you’re probably more comfortable of thinking of speeds in terms of either kilometers per hour (km/h) or miles per hour (mi/h). In this problem, you will see that 1 m/s is roughly 4 km/h or 2 mi/h, which is handy to use when developing your physical intuition. More precisely, show that (a) 1.0 m/s = 3.6 km/h and (b) 1.0 m/s = 2.2 mi/h.

Consider the equation s = s0 + v0t + a0t2/2 + j0t3/6 + S0t4/24 + c0t5/120 , where s is length, and t is time. What are the SI units of (a) s0, (b) v0, (c) a0, (d) j0, (e) S0, and (f) c0? The answers are case sensitive. If you want to insert superscript use the notation "^". For example "m/s^2" means meters per second squared.
