Question

Dimensional Analysis problem:
vf (final velocity) = vi (initial velocity) x t + a
v = meters/second
t = seconds
a = meters/second squared

Answer 1

the above equation is dimentsionly incorrect.........the dimension of each term must be same......but in above equation the dimensions of all three terms is different...
the correct equation is vf= vi+ at

Answer 2

Can you please show me each step in order to understand the problem? believed it to be invalid, however, I don't know that my work successfully shows that I'm understanding the concept. Thanks.

Answer 3

the dimension of vf is m/s....so the dimension of the terms right to the equal to sign must be m/s.....but the dimension of vt is meters as ( meters/second X second )...and dimension of a is m/s^2

Answer 4

Can you work out m/s = 2m/s squared?
