]Okay, so this is my first physics class ever. I'm a little lost, but I believe I'm on the right track. Am I approaching this problem the right way?
-------------Dimension------------------------------Dimension-------
distance (x) (L) Acceleration (a) (L)/(T)^2
Time (t) (T) Force (F) (M)(L)/(T)^2
Mass (m) (M) Energy (E) (M)(L)^2/(T)^2
Speed (v) (L)/(T)
which of the following equations are dimensionally correct?
(A) F=ma (d) E=max
(b) x= at^3/2 (e) v= square root of (Fx/m)
(c) E= mv/2
