Consider the following set of equations, where s, s0 and r have units of length, t has units of time, v has units of velocity, g and a have units of acceleration. Take k to be dimensionless.Identify if these are dimensionally correct or incorrect.

1)v^2= 2as + kav

2)s = s0 + kat^2

3)a =v^2/r+kv/t

4)t =v/a

5)t = k square root of s/g

**Elena**, Tuesday, September 4, 2012 at 11:59am1)v^2= 2as + kav

m²/s²=(m/s²)•m +(m/s²)•(m/s)

=> incorrect

2)s = s0 + kat^2

m= m + (m/s²)•s²=> correct

….

3 incorrect

4 correct

5 correct
