Question

The response for #35 is: The equation is v = 2ax Now, in the SI system, the unit of v is m/s, a ism/s2 and x is m. This is where I am have trouble understanding? Where does thevalues for v, a, and x come from? Here is the original question? One student, using unitanalysis, says that the equation v = 2ax is dimensionallycorrect. Another student says it isn't. With whom do you agree, andwhy? The response for #35 is: The equation is v = 2ax Now, in the SI system, the unit of v is m/s, a ism/s2 and x is m. This is where I am have trouble understanding?

Explanation / Answer

given problem v = 2ax here 2 has now dimensional formula so a = m/s2 , x = m plug   v = m/s2 *m           m/s =m/s this eq is dimensionally correct.
