Best ResponseYou've already chosen the best response.0a. We know V0, V, and T so I pick the equation \[V = V_0 +at\] Plugging them all in I get 5.4167 m/s^2 b. Now the distance... we know those 4 variables now. I pick the equation \[X = 1/2(V_0+V)T\] Plug and chug, I get X = 690. You can even try b with other equations if you're feeling adventurous to make sure the answer is right! Hope that helps!

Best ResponseYou've already chosen the best response.0Eep, sorry I didn't convert any units! So converting units we end up with a. 5416.66 m/s^2 b. 690000 m

Best ResponseYou've already chosen the best response.0something isn't right.. I understand exactly what you're saying but it's calling it wrong

Best ResponseYou've already chosen the best response.0That's odd, I apologize. Did it again though and got the same thing though. Hopefully someone can catch the issue here...

Best ResponseYou've already chosen the best response.0Ah maybe it's part a. It asks to round to 3 decimal places and I didn't notice that (rounding is the death of me) So rounded to 3 decimal places it's "5416.667"
